+saikiran paladugdula You disabled replies, but here is my attempt:

import math #if i don't do this, i get an error message

#the number of sides has to be an integer:
n = int(input('Number of sides: '))
#the length of the side could be any rational number, e.g. 1.5342654:
s = float(input('Length of each side: '))

# calculate the area:
area =
# calculate the perimeter:
perimeter = n*s

# calculate funsum, and round it to 4 decimal places:
funsum = round((area + perimeter**2)*10**4)/10**4

'''convert s into an integer, but only if it's a whole number
e.g. 7.0 gets converted to 7, but 7.1 stays as it is.
If I don't do this, the print function at the end treats an integer value
as a floating point, so i get
>Funsum(5, 7.0) = 1309.3034 (4 decimal places).
'''
if s%1 == 0:
s = int(s)

#print:
print('Funsum('+str(n)+', '+str(s)+') = '+str(funsum)+' (4 decimal places).')

Hello. I tried these in Shell and all is well. However, when I try to write a very simple program it does not recognise the ^ (xor) symbol. Can you help? My program is as follows:

#We shall Xor two binary strings

print('Enter a 4-bit string p1 = ')
# For example, I enter 0b1111
p1 = input()

print('Enter a 4-bit string a1 = ')
# For example, I enter 0b1001
a1 = input()

# up to here everything is fine, but then...

print(bin(p1^a1))
# This last line of code causes an error message,
# though it works fie in 'Shell' why does it fail now?
# my thanks in advance

what will be the output of
a=10
b=15
a and b

please explain...
