0x00 错误

Traceback (most recent call last):File "/Users/apple/Desktop/Me/My/Python3/MyCode/test.py", line 43, in <module>test()File "/Users/apple/Desktop/Me/My/Python3/MyCode/test.py", line 13, in tests = str(count)
UnboundLocalError: local variable 'str' referenced before assignment

0x01 代码

代码：

import requests
from bs4 import BeautifulSoup as bsdef test():count = 0while True:count += 1s = str(count)print('第 ' + s + ' 次')breakprint('begin...')headers = {'user-agent':'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.109 Mobile Safari/537.36'}url = 'https://www.xxx.xxxx'r = requests.get(url, headers = headers)soup = bs(r.text, 'lxml')kk = soup.find(class_='xxxxx')str = kk.textarr = str.split('个')if len(arr) == 2:count = arr[0]if len(count) > 0:if int(count) > 10:print(str)if __name__ == '__main__':test()

数字转字符串不就是这样么？

count = 0
str(count)

全局搜索了一下代码
原来在后面定义了一个 str 变量
这个变量，覆盖了系统的类 str
所以，导致了
UnboundLocalError: local variable 'str' referenced before assignment

0x02 办法

既然是命名覆盖，那就换个名字好了~
要注意的一件事情是：
不要跟系统的类重名了！
