如果条件为 False，如何打破 while 循环？

Question

I have a long function in which I am checking for different parameters and if any of the parameters is False, I don't want to execute the code further.

For your understanding, this is how I want to make it work

Email = True
while(Email == True):
    print("Execute Me")
    Email = False # Break the while loop here
    print("Never execute me")

Here is the pseudo version of my code:

def users_preferences(prefs):
    for pref in prefs:
        send_email = True
        while(send_email == True):
            # Set send_email = False if email is not verified and don't move to the next line
            # Set send_email = False if user's email is not a part of specific group
            ...
            ...

How can I break the loop if the condition is False at any point without further executing the code?

Edit: The problem with break statements is that it will become cumbersome to check the condition before running a new statement where you have number of statements

Answer 1

You can use a normal break statement:

Email = True
while Email:
    print("Execute Me")
    Email = False # Break the while loop here
    if not Email:
        break
    print("Never execute me")

Edit: If the while loop doesn't do anything special, the code can be modified to be:

for pref in prefs:
    if not is_email_verified(email) or not is_user_in_group(user, group):
        continue
    send_email(email)

Hello your code needs to be better indented. Also why haven't you tried using break statement to get out of the loop?

Email = True
while Email:
    # do something
    break
# continue doing something
