Python I'；运行代码时出错（语法无效）

这是我的密码

在运行时，我得到一个“无效语法”错误，我使用的是Python/IDLE 3.4.2。 这只是一个学校项目的小程序，我有一个错误

我想这可能是缩进的问题，但我不确定，是否需要任何帮助：）

要继续Jim所说的，您的代码应该是

import time
def pini():
    pin1 = int(input("enter your pin please: ")
    if pin1 == pin:
            print("pin correct")
            print("paying: £",amount)
            print("opening connection...")
            time.sleep(0.4)
            print("contacting bank...")
            time.sleep(1.0)
            print("contacting bank...")
            time.sleep(0.5)
            print("contacting bank...")
            time.sleep(0.2)
            print("contacting bank...")
            time.sleep(0.2)
            print("transaction successful")
    elif:
            print("wrong pin, try again")
            pini()

print("Welcome to the bank")
print("\n")
pin = int(input("what is your pin: ")

pay = ""
while pay == "":
    pay = input("press 'n' to make a payement: ").lower()
    if pay == "n":
            amount = int(input("please enter amount to pay: ")
            print("please insert your card to pay" , "£",amount)
            print("\n")
            pini()

您可能想考虑使用IDE——因为这些可以突出显示像这样的简单错误（例如，Eclipse是我的选择）。询问哪一个是最好的-

我在代码中添加了一些注释，如下所示

def pini():
    pin1 = int(input("enter your pin please: "))

)在inputIn all

int（input（“”）

调用中缺少。您忘了关闭外圆括号。例如，在所有

int（input（“”）调用中，inputIn中缺少
int（input）（“）
