我如何在需要时要求输入变量，而不是在每行之前输入input（）？

Question

How do I make it so if this variable is needed, it'll ask for the input of this variable?

"""imports"""
import math
"""def"""
def rectArea:
    return A = l * b
def rectPeri:
    return P = 2 * (l+b)
def squareArea:
    return A = l*l
def squarePeri:
    return P = l * 4
def parallelogramArea:
    return A = l * h
def parallelogramPeri:
    return P = 2 * (l+b)

For example in rectArea , length( l ) and breadth( b ) are needed, so it would ask for an input of the l and b variables?

Answer 1

对于用户输入，请使用input()方法。

length = input("Enter rectangle length: ")
