Python: Test if a variable is a list or tuple or a set

Python Basic: Exercise-145 with Solution

Write a Python program to test if a variable is a list or tuple or a set.

Sample Solution-1:

Python Code:

#x = ['a', 'b', 'c', 'd']
#x = {'a', 'b', 'c', 'd'}
x = ('tuple', False, 3.2, 1)
if type(x) is list:
    print('x is a list')
elif type(x) is set:
    print('x is a set')
elif type(x) is tuple:
    print('x is a tuple')    
else:
    print('Neither a list or a set or a tuple.')

Sample Output:

x is a tuple

Sample Solution-2:

Python Code:

def check_type(nums):
    if isinstance(x, tuple)==True:
        return 'The variablex is a tuple'
    elif isinstance(x, list)==True:
        return 'The variablex is a list'
    elif isinstance(x, set)==True:
        return 'The variablex is a set'
    else:
        return 'Neither a list or a set or a tuple.'
x = ['a', 'b', 'c', 'd']
print(check_type(x))
x = {'a', 'b', 'c', 'd'}
print(check_type(x))
x = ('tuple', False, 3.2, 1)
print(check_type(x))
x = 100
print(check_type(x))

Sample Output:

The variablex is a list
The variablex is a set
The variablex is a tuple
Neither a list or a set or a tuple.

Python: Tips of the Day

Unpack variables from iterable:

# One can unpack all iterables (tuples, list etc)
>>> a, b, c = 1, 2, 3
>>> a, b, c
(1, 2, 3)

>>> a, b, c = [1, 2, 3]
>>> a, b, c
(1, 2, 3)
