UnboundLocalError: local variable 'count' referenced before assignment python
我正在为 Telegram Bot 编写代码。我想输入一系列图像作为输入。为此，我使用计数器变量 count = 0 来计算图像的数量。但是，我在输入第二张图片时出现异常，依此类推。异常说我的变量被引用为局部变量，而我将其设为全局变量。
可能是什么问题？

你需要使用
global count
在分配给 count
的每个函数中
def gender(bot, update):
global count
...
和
def main():
global count
...
最好避免全局。只需在 main 中使 count 成为局部变量，然后将其传入和传出性别等
def gender(bot, update, count):
...
return count
