怎么if __name__ == "__main__":办？

# Threading example
import time, thread

def myfunction(string, sleeptime, lock, *args):
    while True:
        lock.acquire()
        time.sleep(sleeptime)
        lock.release()
        time.sleep(sleeptime)

if __name__ == "__main__":
    lock = thread.allocate_lock()
    thread.start_new_thread(myfunction, ("Thread #: 1", 2, lock))
    thread.start_new_thread(myfunction, ("Thread #: 2", 2, lock))

def main():
   names = []
   for line in ins:
       number_strings = line.split() # Split the line on runs of whitespace
       data.append(numbers_strings) # Add the "row" to your list.
       print(data)

我尝试使用此代码打印看起来像这样的文本文件

name num1 num2 C/N

我试图打印这个但是当我运行命令"python3 file.py"时没有输出.而不是打印我正在放入的文件的内容

当我运行程序并输入性别作为其他任何东西但不是男性或女性时,该程序不能按预期工作.我已经挣扎了一天,无法弄清楚.另外如何在调用之后放置函数并仍然使程序运行？我读了一个main函数,但无法弄清楚如何用它修改代码.

from sys import exit
birthdays = {'Alice': 'April 1', 'Bob': 'Dec 12', 'Carol': 'Mar 4'}

def dateOfBirth():
    bday = raw_input("> ")
    birthdays[name] = bday
    print "Database records updated."
    print "The number of records is now " + str(len(birthdays)) + "."
    print birthday`enter code here`s
    exit(0)

while True:
    print "Enter a name: (blank to quit)"
    name = raw_input("> ")

    if name == '':
        exit(0)

    if name in birthdays:
        print birthdays[name] + " is the birthday of " + name + …
