python:没有输出或只产生一个空列表 [英] python : no output or only an empty list was produced

问题描述

index1 = 0
singlechar = []
def SINGLE_CHAR_VAR(filename):
    firdict = vars_indents(filename)[0]
    firtup_keys = firdict.keys()
    firtup_val = firdict.values()
    for keys in firtup_keys:
        for values in firtup_val:
            index = 0
            for index in range(len(values)):
                firvallist = firtup_val[index]
                for item in firvallist:
                    if len(item[0]) == 1:
                        singlechar.append({'ERROR_TYPE': 'SINGLE_CHAR_VAR', 'LINE_NUMBER': str(keys),'COLUMN': str(item[1]),'INFO': str(item[0]),'SOURCE_LINE': str(lines[keys - 1])})
                    else:
                        continue
                return singlechar

这是我的代码，但没有产生任何输出，或者当我在 return 语句周围移动时，产生了一个空列表.我希望它能给我一个字典列表作为输出.

this is my code but there is no output produced or when i move around the return statement an empty list was produced. i was hoping it to give me a list of dictionaries as the output.

有人可以教我如何解决这个问题吗?

can somebody teach me how to fix this?

谢谢

推荐答案

您应该首先调用该函数以获取输出.

You should call the function at first to get the output.

SINGLE_CHAR_VAR(filename)

你怎么能期望一个函数在不被调用的情况下运行?
