我的问题是,每当我的程序遍历for循环时,是否有可能更改它正在处理的字典(在本例中是向中添加信息)。i、 它第一次遍历dict\ u1,然后遍历dict\ u2等等
def getDicts(aFile):
voteFile = open(aFile)
listDicts = [{},{},{},{},{},{},{},{},{},{},{}]
i = 0
for line in voteFile:
lineSplit = line.split(':')
if len(lineSplit) > 1:
key = lineSplit[0].strip()
value = lineSplit[1].strip()
listDicts[i][key] = value
else:
i += 1
return listDicts
程序正在处理的文件包含文本块,其中每行有两个用冒号分隔的项。每个街区后面都有一条新线。这就是为什么当每行上的项的长度不是2时会有while循环检查的原因。当程序退出while循环时,我希望它将完成的字典(dict\ u 1)添加到字典列表中,然后在.txt文件中的下一个文本块上重新开始,这次将信息添加到dict\ u 2。你知道吗

作为一名计算机科学家,我个人喜欢保持从0开始而不是从1开始的惯例。例如,dict1到dict11现在是dict0到dict10。你知道吗
我不知道为什么在代码中使用while循环,我认为if语句就足够了。你知道吗
不管怎样,这里有一些代码给你。它只使用较少数量的字典,但它应该符合您的要求(假设您总是有11行数据后跟一个空行)。你知道吗
顺便说一下,%是一个模除运算符。它返回剩余的股息。因此5%4=1和4%3=1
测试.txt
脚本
编辑此算法没有嵌套循环,因此运行时为O(n),其中n是输入文档中的每一行。你知道吗
以下是我的建议:
访问信息就是查询选区的问题:
我还建议您从Pandas开始将数据排序为数据帧—这将使您的数据处理变得更加轻松
欢迎其他用户提出建议和反馈。你知道吗
