我有一个学校项目,我的程序必须执行此代码才能跟随两个用户:
def followWithUsername(self):
usernames = ['therock', 'justinbieber']
self.driver.get('https://instagram.com/' + str(usernames) + '/')
time.sleep(3)
followButton = self.driver.find_element_by_css_selector('button')
if (followButton.text != 'Following'):
followButton.click()
time.sleep(3)
else:
print("You are already following this user.")
我尝试了各种方法,但这不会将用户名彼此分开并一一执行]
使用for
循环:
def followWithUsername(self):
usernames = ['therock', 'justinbieber']
for name in usernames:
self.driver.get('https://instagram.com/' + name + '/')
time.sleep(3)
followButton = self.driver.find_element_by_css_selector('button')
if (followButton.text != 'Following'):
followButton.click()
time.sleep(3)
else:
print("You are already following this user.")
您需要遍历列表才能对多个值执行此操作。鉴于这是一个学校项目,所以我很乐意为您提供完整的答案。
最好通过使用for loops
来实现,您可以在此处阅读更多有关这些的信息:Python FOR Loops
您将遇到并大量使用for
循环,在这里,它们是非常有用的一个例子:
values = [1,2,3,4,5,6,7,8,9,10]
# This translates to "For each item stored in the list 'values' perform the following code"
for item in values:
print(item)
1
2
3
4
5
6
7
8
9
10
