python中的for循环内x = x + 1语法错误

Question

如果条件满足，我试图在for循环中增加一个变量（计数）。但是，在递增语句中出现语法错误。请帮忙。

def count_ans():
    count=0
    for m in range(0,4):
        if quiz_dict[q_nos[m]==ans_list[m]:
            count += 1    #<--syntax error
return count

Answer 1

Folllwong应该是函数

def count_ans（）：

count=0
for m in range(0,4):
    if quiz_dict[q_nos[m]]==ans_list[m]:  ##### Square bracket was missing
        count += 1   
return count                        #### Return was outside the function
