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, tuple, or set.

Sample Solution-1:

Python Code:

#x = ['a', 'b', 'c', 'd']
#x = {'a', 'b', 'c', 'd'}
# Define a variable x with different data types (list, set, or tuple).
x = ('tuple', False, 3.2, 1)

# Check the type of x using the 'type()' function and print a message accordingly.
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 nor a set nor a tuple.')

Sample Output:

x is a tuple

Sample Solution-2:

Python Code:

# Define a function to check the type of a variable 'nums'.
def check_type(nums):
    # Check if 'nums' is a tuple and return a message.
    if isinstance(x, tuple) == True:
        return 'The variable x is a tuple'
    # Check if 'nums' is a list and return a message.
    elif isinstance(x, list) == True:
        return 'The variable x is a list'
    # Check if 'nums' is a set and return a message.
    elif isinstance(x, set) == True:
        return 'The variable x is a set'
    # If 'nums' is none of the above types, return a generic message.
    else:
        return 'Neither a list or a set or a tuple.'

# Define a variable 'x' as a list and check its type using the 'check_type' function.
x = ['a', 'b', 'c', 'd']
print(check_type(x))

# Define a variable 'x' as a set and check its type using the 'check_type' function.
x = {'a', 'b', 'c', 'd'}
print(check_type(x))

# Define a variable 'x' as a tuple and check its type using the 'check_type' function.
x = ('tuple', False, 3.2, 1)
print(check_type(x))

# Define a variable 'x' as an integer and check its type using the 'check_type' function.
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.
