在for循环中使用布尔值

Question

到目前为止，我有一个while循环，但我想知道如何在for循环中检查某些内容。

到目前为止我看到的是这样的：

i = 0
found = False
while ((i < len(my_string)) and (not found))
    my_char = my_string[i]
    if my_char in my_set:
        found = True
    elif my_char == 'x':
        i = helper_function(my_string, i)
    else:
        i += 1
return i

不确定帮助函数正在做什么，但这将是for循环看起来的基本要点

i = 0
for char in my_string:
    if my_char in my_set:
        break
    elif my_char == 'x':
        i = helper_function(my_string, i)
    else:
        i += 1
else:
    pass ## put logic here if you need the code to do something if the char wasn't found
return i
