在Python中从一个函数调用变量到另一个函数

Question

我正在编写一个程序来通过python发送电子邮件。我有不同的定义，其中包含包含电子邮件用户名和电子邮件密码等的变量。然后我有另一个定义，实际发送电子邮件，但它需要包含电子邮件用户名和密码等的变量。如何调用来自不同def的变量？对不起，措辞怪异。我不知道该怎么说：P谢谢！

def get_email_address():
    #the code to open up a window that gets the email address
    Email = input
def get_email_username():
    #the code to open up a window that gets email username
    Email_Username = input

    #same for the email recipient and email password

def send_email():
    #here I need to pull all the variables from the other def's
    #code to send email

Answer 1

您将需要在辅助函数中返回值并从主send_email()函数中调用这些函数，并将返回的值分配给变量。像这样：

def get_email_address():
    #the code to open up a window that gets the email address
    Email = input
    return Email

def get_email_username():
    #the code to open up a window that gets email username
    Email_Username = input
    return Email_Username

#same for the email recipient and email password

def send_email():
    # variables from the other def's
    email_address = get_email_address()
    email_username = get_email_username()

    #code to send email
