try and except keywords are used in Python for try and catch. Indentation plays an important role in try and catch statements in Python.

Example:

#Expecting age value from the employee
strAge = input(
    'Please share your age'
);
try:
    #Converting string to integer
    intAge = int( strAge );
    #Printing the voting ability
    if intAge < 18 :
        print(
            'You are not eligible for voting.'
        );
    elif intAge <= 58:
        print(
            'You are eligible for voting.'
        );
    else :
        print(
            'You are a senior citizen with Voting rights.'
        );
except:
    print( 
        'You have entered incorrect age value' 
    );
print( 'Thank you!' );
