What am i doing wrong - math tool box

[vishalhule]

do indentation properly

ans=True
while ans:
    print("""
    1.Square
    2.Rectangle
    3.Triangle
    4.Circle
    5.Exit the program
    """)
    ans=input("What would you like to do?")
    ans = ans.strip()
    if ans=='1':
        print("""Square is selected.""")
        side = int (input("Now input side"))
        print ("Area is", side*side)
        print ("Circumference is",4*side)
    

you can do for other cases also
by defalultinput() function converts userinput into string.
