I guess it's about print - tsavoSG - Feb-07-2021

code:

money=1000
取款=int(input('请输入取款金额：'))
if 取款<=money:
    print('请拿好钞票',取款)
    print('账户余额为：', money = money-取款)
else:
    print('余额不足，现有：', money)
    print('请再次输入取款金额：')
result
Error:
请输入取款金额：350
请拿好钞票 350
Traceback (most recent call last):
  File "E:\2018.1.1\Python\4 if.py", line 5, in <module>
    print('账户余额为：', money = money-取款)
TypeError: 'money' is an invalid keyword argument for print()
so when print, money = money - withdraw is causing trouble, right?

yes
print('账户余额为：', money-取款)
you better look at f-strings or str.format methods

I think the problem is you cant do a calculation where you put it,
so put the calculation money = money-取款
on a separate line and it appears to work:

money=1000
取款=int(input('请输入取款金额：'))
if 取款<=money:
    print('请拿好钞票',取款)
    money = money-取款
    print('账户余额为：', money)
else:
    print('余额不足，现有：', money)
    print('请再次输入取款金额：')
