Python文件到字典，其中包含键值对的特定子字符串

Question

我有一个文本文件，看起来像：

AAAAA123123423452452BBBASDASAS323423423432
BBBBB453453453466123AAAAADDFFG6565656565665

我想用它创建一个字典，每一行的各个部分都有如下键：

文件.txt：

hash[123123] = "BBBASD"
hash[453453] = "AAAAAD"

我已经写了下面的尝试，但到目前为止还不起作用。不打印任何内容：

myhash{}
with open('file.txt') as fi:
    for life in fi:
        key = [line:6:13]
        value = [line:21:27]
        myhash[key] = value

print(myhash) 

有人能帮忙吗？提前谢谢

Answer 1

您应该使用：

myhash = {}
with open('file.txt') as fi:
    for line in fi.readlines():
        key = line[5:11]
        value = line[20:26]
        myhash[key] = value

print(myhash)
