I'm brand new to python and I don't understand why it displays this error when I try to multiply by something with a decimal

Answer 1

这应该是float类型，而不是int类型。

Answer 2

In Python and elsewhere, ints are only whole numbers. 1.5, 1.2, pi, anything with a decimal is not an int. You want float to describe them. It's short for floating point number.

Answer 3

change to : int(float(input("Enter portion of heigh in inches")))

str to float to int should work if str is something like 1.333

str to int only works when str is an integer like 4
