Variable Type Checker

Write a Python program to check whether a variable is an integer or string.

Sample Solution-1:

Python Code :

# Check if 25 is an instance of an integer (int) or a string (str).
print(isinstance(25, int) or isinstance(25, str))

# Check if the list containing 25 is an instance of an integer (int) or a string (str).
print(isinstance([25], int) or isinstance([25], str))

# Check if the string "25" is an instance of an integer (int) or a string (str).
print(isinstance("25", int) or isinstance("25", str))

Sample Output:

True                                                                    
False                                                                   
True

Sample Solution-2:

Python Code :

# Define a function 'test' that takes a parameter 'n'.
def test(n):
    # Check if the type of 'n' is equal to 'int'.
    if type(n) == int:
         # If 'n' is an integer, return the message "It is an integer!"
         return "It is an integer!"
    else:
         # If 'n' is not an integer, return the message "It is a String!"
         return "It is a String!"     

# Call the 'test' function with an integer argument (12) and print the result.
print(test(12))

# Call the 'test' function with a string argument ('23312') and print the result.
print(test('23312'))

Sample Output:

It is an integer!
It is a String!
