python问题 两篇一模一样的代码一篇可以运行一边却运行不了
而且全篇代码都没有报错的地方

import math

functions = ('e', 'pi', 'sin', 'cos', 'tan', 'sqrt', 'radians')


def calculate(expression):
    expression=expression.lower()
    #low()
    expression = expression.replease('%', '/100.0')
    expression = expression.replease('^', '**')
    expression = expression.replease('mod', '%')
    expression = expression.replease('rad', 'radians')

    for i in functions:
        if i in expression:
            expression=expression.replease(i, 'math.{}'.format(i))
    try:
        return (eval(expression))
    except ZeroDivisionError:
        print('zero can not be division')
    except Exception as e:
        print(e)


def main():
    while True:
        expression = input('input your expression here:')
        if expression == 'q':
            break
        else:
            result = calculate (expression)
            if result:
                print(result)


if __name__ == "__main__":
    main()

Answer 1

replace吧，replease是什么鬼？
please是请，re-please是重新请？
