Question

嗨我相当新的python并且无法在此程序中发现我的错误，我的错误看起来像这样

TypeError：hitormiss（）缺少1个必需的位置参数：＆＃39; totalaim＆＃39;

#!usr/bin/python3
import random

def takeshot(prompt='do you want to take shot?\n'):
answer = input(prompt)
    if answer == ['yes', 'y']:
        print("taking shot...")
    else:
        print("not-working")

def cal(randomnum = random.randrange(0, 100) , baseaim = 15):
    totalaim = randomnum + baseaim
    return totalaim




def hitormiss(totalaim, hit=50):
    if totalaim >= hit:
        print("You have hit your target!")
    elif totalaim < hit:
        print("You have missed your target!")
    else:
        print("Revise Code.")



takeshot()
cal()
hitormiss()

totalaim还没有在cal中声明吗？

Answer 1

您应该删除cal()和hitormiss()函数调用，并将其替换为：

hitormiss(cal())

这是因为必须将参数传递给hitormiss()，而cal()会返回totalaim值。

Answer 2

此外，cal.totalaim无法按照您的计划方式解决

def hitormiss(totalaim, hit=50):
    if totalaim >= hit:
        print("You have hit your target!")
    elif totalaim < hit:
        print("You have missed your target!")
    else:
        print("Revise Code.")

然后按照建议打电话

takeshot()    
hitormiss(cal())

python函数错误：键入错误
