Question

我有一个变量：

user = "jobrr"

我想循环以下但是改变每个循环周期后变量所代表的内容（因此在循环中预先确定了即将到来的循环的变量是什么）

example loop as long as y = true
    openurl = urllib.urlopen("https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&contributor_details&include_rts=true&screen_name="+user+"&count=3600")
    user = user + "a" #just for example

我该怎么做？

Answer 1

user = 'username'
y = True

while y:
    openurl = urllib.urlopen("https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&contributor_details&include_rts=true&screen_name="+user+"&count=3600")
    user += "a"
    #You have to do something in here to change y or this will be an infinite loop

Answer 2

user = 'username'
y = True

while y:
    openurl = urllib.urlopen("https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&contributor_details&include_rts=true&screen_name="+user+"&count=3600")
    user = function_that_returns_user_name()

您只需要定义function_that_returns_user_name()

在循环中更改变量
