More Than 100 Python Exercises Have Solutions (Sample Code)

This guide covers more than 100 python exercises have solutions (sample code) with practical context and easy-to-follow details. Use it to understand the subject and apply the information confidently.

Note: The sample code in the article is written in Python 3. 6. 2, if you are using Python version 2. 5 or below it may not run the code because in the new Python version many commands, the function has been changed.

This Python exercise will be divided into 3 levels for beginners to learn programming, who have learned programming but who have just learned Python and who want to improve Python proficiency. Each exercise has a full set of requirements, lesson suggestions, and solution (sample code), which is a sample Python code for your reference. Now invite you to open the specific content.

Level 1: The person who has just taken an overview of Python, can solve some problems with 1, 2 classes or Python functions. Exercises of this level can be found in regular textbooks and instructional materials.

Level 2: New learner of Python but already has a relatively powerful programming platform that can solve problems related to 3 classes or Python functions. These exercises are often not found in textbooks.

Level 3: Enhance, use Python to solve more complex problems by using rich functions, data structures and algorithms. At this level you can solve problems using several standard Python packages and advanced programming techniques.

Each Python exercise in this page will include the following 3 sections:

Question.
Suggestions.
Sample code.

I will leave the original form like this, you can see the questions and suggestions then practice yourself before pulling down to see the sample code.

Lesson 01:

Question:

Write a program to find all numbers divisible by 7 but not multiples of 5, located in paragraphs 2000 and 3200 (including 2000 and 3200). The obtained numbers will be printed in series on one line, separated by commas.

Suggestions:

Use range (#begin, #end)

Sample code:

j=[]
for i in range(2000, 3201):
 if (i%7==0) and (i%5!=0):
 j.append(str(i))
print (','.join(j))

Lesson 2:

Question:

Writing a program can calculate the factorial of a given number. The result is printed in series on a line, separated by commas. For example, the given number is 8, the output must be 40320.

Suggestions:

In case the input data is provided, please choose a way for the user to enter the number.

Sample code:

x=int(input("Nh?p s? c?n t�nh giai th?a:"))
def fact(x):
 if x == 0:
 return 1
 return x * fact(x - 1)
print (fact(x))

Lesson 03:

Question:

For a given integer n, write a program to create a dictionary containing (i, i * i) as an integer between 1 and n (including 1 and n) and then print this dictionary. Example: Suppose the number n is 8, the output will be: {1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64}.

Suggestions:

Write a command that requires an integer n.

Sample code:

n=int(input("Nh?p v�o m?t s?:"))
d=dict()
for i in range(1,n+1):
 d[i]=i*i

print (d)

Lesson 04:

Question:

Write a program that accepts a sequence of numbers, separated by commas from the console, creates a list and a tuple containing all numbers.

Example: The input provided is 34, 67, 55, 33, 12, 98, the output is:

['34', '67', '55', '33', '12', '98'] ('34', '67', '55', '33', '12', '98')

Suggestions:

Write a command to enter the values and then use the data type conversion rule to complete.

Sample code:

values=input("Nh?p v�o c�c gi� tr?:")
l=values.split(",")
t=tuple(l)
print (l)
print (t)

Lesson 05:

Question:

Define a class with at least 2 methods:

GetString: to receive a string entered by the user from the console.

PrintString: print the string just entered in uppercase.

Add simple risk functions to test the method of the class.

Example: The input string is TipsMake. Com, the output must be: TipsMake. Com

Suggestions:

Use __init__ to build parameters.

Sample code:

class InputOutString(object):
 def __init__(self):
 self.s = ""

 def getString(self):
 self.s = input("Nh?p chu?i:")
 # Code by TipsMake.com 
 def printString(self):
 print (self.s.upper())

strObj = InputOutString()
strObj.getString()
strObj.printString()

Lesson 06:

Question:

Write a method that calculates the square value of a number.

Suggestions:

Use operator **.

Sample code:

x=int(input("Nh?p m?t s?:")) #nh?p s? c?n t�nh b�nh ph??ng t? giao di?n
def square(num): #??nh ngh?a b�nh ph??ng c?a m?t s?
 return num ** 2
 # Code by TipsMake.com 
print (square(2)) #in b�nh ph??ng c?a 2
print (square(3)) #in b�nh ph??ng c?a 3
print (square(x)) #in b�nh ph??ng c?a x

Since the problem does not specifically require you to calculate the number of squares available or the number entered, I use both.

Lesson 07:

Question:

Python has many built-in functions, if you don't know how to use it, you can read the documentation online or find some books. But Python also has function documentation available for every Python built-in function. The requirement of this exercise is to write a program to print documents on some of the built-in Python functions such as abs (), int (), input () and add documents for the function you define yourself.

Suggestions:

Use __doc__

Sample code:

print (abs.__doc__)
print (int.__doc__)
print (input.__doc__)
 # Code by TipsMake.com 
def square(num):
 '''Tr? l?i gi� tr? b�nh ph??ng c?a s? ???c nh?p v�o.

 S? nh?p v�o ph?i l� s? nguy�n.
 '''
 return num ** 2

print (square.__doc__)

Lesson 08:

Question:

Defining a class includes class parameters and has the same instance parameter

Suggestions:

When defining an instance parameter, it needs to be added to __init__
You can initialize an object with the start parameter or set the value later.

Sample code:

class Person:
 # ??nh ngh?a l?p "name"
 name = "Person"
 # Code by TipsMake.com 
 def __init__(self, name = None):
 # self.name l� bi?n instance
 self.name = name

jeffrey = Person("Jeffrey")
print ("%s name is %s" % (Person.name, jeffrey.name))

nico = Person()
nico.name = "Nico"
print ("%s name is %s" % (Person.name, nico.name))

Lesson 09:

Question:

Write a program and print the value according to the given formula: Q = ([(2 * C * D) / H]) (in words: Q equals the square root of [(2 kernels C kernel D) divided H] With a fixed value of C of 50, H is 30. D is a range of custom values, entered from the user interface, the values of D are separated by commas.

Example: Assuming the value chain of D entered is 100, 150, 180, the output will be 18, 22, 24.

Suggestions:

If the output received is a decimal number, you need to round it to the nearest value, for example 26. 0 will be printed as 26.
In case the input data is provided for the question, it is assumed that the input is entered by the user from the console.

Sample code:

#!/usr/bin/env python
import math
c=50
h=30
value = []
items=[x for x in input("Nh?p gi� tr? c?a d: ").split(',')]
for d in items:
 value.append(str(int(round(math.sqrt(2*c*float(d)/h)))))
 # Code by TipsMake.com 
print (','.join(value))

Lesson 10:

Question:

Write a 2-digit, X, Y program that gets the value from the input and creates a 2-dimensional array. The element value in the ith row and jth column of the array must be i * j.

Note: i = 0. 1, ., X-1; j = 0. 1, ., Y-1.

Example: Input X and Y value is 3. 5 then output is: [[0, 0, 0, 0, 0], [0, 1, 2, 3, 4], [0, 2, 4, 6, 8]]

Suggestions:

Write a command to get X, Y values from the user-input console.

Sample code:

input_str = input("Nh?p X, Y: ")
dimensions=[int(x) for x in input_str.split(',')]
rowNum=dimensions[0]
colNum=dimensions[1]
multilist = [[0 for col in range(colNum)] for row in range(rowNum)]

Suggestions:

Use dict [key] = value to import entries into dictionary.
Use the Word ** to get the square of a number.
Use range () for loops.
Use keys () to iterate the keys in the dictionary. You can use item () to get key / value pairs.

Sample code:

def printDict():
 d=dict()
 for i in range(1,21):
 d[i]=i**2 
 for (k,v) in d.items():
 print (v)
# B�i t?p Python 34, Code by TipsMake.com

Use the ** operator to get the square value.
Use range () for the loop.
Use list. Append () to add values to the list.
Use [n1: n2] to cut the list

Sample code:

def printList():
 li=list()
 for i in range(1,21):
 li.append(i**2) 
 print (li[:5])
# B�i Python 37, Code by TipsMake.com 
 printList()

Running the above code you will get a list containing the square value of the numbers from 1 to 5.
