a = int(float(input("Add : ")))
b =  int(float(input("Add : ")))
c = print(" = " , a**2   b**2)

print(c/2)

I'm going to divide the variable and the number but it happens like this, how do I fix it? | TypeError: unsupported operand type(s) for /: 'NoneType' and 'int'

CodePudding user response：

print returns None, which you assign to c. None can't be divided by an int, hence your error.

If you want to store the result of a**2 b**2 in c, then do so directly:

a = int(input("Add: "))
b = int(input("Add: "))
c = a**2   b**2

print(f"{a=}, {b=}, {c=}")
print(c / 2)

Sample output:

Add: 3
Add: 5
a=3, b=5, c=34
17.0

CodePudding user response：

print is a function which returns None and the side effect of printing its args to stdout. Therefore c has the value None. And None / 2 gives the TypeError
