Syntax of set () function in Python

set([iterable])

Parameters of the set () function

Python's set () constructor has a single parameter:

• iterable(optional): objects can be string, tuple, set, list, dictionary. .or iterator object .

The value returned from set

• If no parameters are passed, set () creates an empty set.
• If iterable is passed as a parameter, it will create a set of elements in iterable.

Example 1: Create a collection from string, tuple, list, range

# t?p h?p r?ng print(set()) # string print(set('Python')) # tuple # vi?t b?i TipsMake.com print(set(('a', 'e', 'i', 'o', 'u'))) # list print(set(['a', 'e', 'i', 'o', 'u'])) # range print(set(range(5)))

Running the program, the result is returned:

set() {'P', 'o', 't', 'n', 'y', 'h'} {'a', 'o', 'e', 'u', 'i'} {'a', 'o', 'e', 'u', 'i'} {0, 1, 2, 3, 4}

Example 2: Create a collection from set, dictionary and frozen set

# set print(set({'a', 'e', 'i', 'o', 'u'})) # dictionary # vi?t b?i TipsMake.com print(set({'a':1, 'e': 2, 'i':3, 'o':4, 'u':5})) # frozen set frozenSet = frozenset(('a', 'e', 'i', 'o', 'u')) print(set(frozenSet))

Running the program results in:

{'a', 'o', 'i', 'e', 'u'} {'a', 'o', 'i', 'e', 'u'} {'a', 'o', 'e', 'u', 'i'}

Example 3: Creating a collection from an iterator object

class PrintNumber: def __init__(self, max): self.max = max def __iter__(self): self.num = 0 return self def __next__(self): if(self.num >= self.max): raise StopIteration self.num += 1 return self.num printNum = PrintNumber(5) # t?o set # vi?t b?i TipsMake.com print(set(printNum))

Running the program results in:

{1, 2, 3, 4, 5}
