Python读取.txt文件->列表 [英] Python read .txt File -> list

问题描述

我有一个.txt文件，我想获取列表中的值.txt文件的格式应为:

I have a .txt File and I want to get the values in a list. The format of the txt file should be:

value0,timestamp0
value1,timestamp1
...
...
...

最后，我想获得一个带有

In the end I want to get a list with

[[value0,timestamp0],[value1,timestamp1],.....]

我知道很容易获得这些值

I know it's easy to get these values by

direction = []
for line in open(filename):
    direction,t = line.strip().split(',')
    direction = float(direction)
    t = long(t)
    direction.append([direction,t])
return  direction

但是我有一个大问题:创建数据时，我忘记在每一行中插入一个"\ n".

But I have a big problem: When creating the data I forgot to insert a "\n" in each row.

这就是为什么我使用这种格式:

Thats why I have this format:

value0, timestamp0value1,timestamp1value2,timestamp2value3.....

每个时间戳记都有13个字符.

Every timestamp has exactly 13 characters.

是否可以根据需要在列表中获取这些数据?再次获取数据将是很多工作.

Is there a way to get these data in a list as I want it? Would be very much work get the data again.

谢谢最高

推荐答案

我使用您的示例编码了一个快捷方式，而不是使用13，而是使用len("timestamp")，以便您可以适应

I coded a quickie using your example, and not using 13 but len("timestamp") so you can adapt

instr = "value,timestampvalue2,timestampvalue3,timestampvalue4,timestamp"

previous_i = 0
for i,c in enumerate(instr):
    if c==",":
        next_i = i+len("timestamp")+1
        print(instr[previous_i:next_i])
        previous_i = next_i

输出已解密:

value,timestamp
value2,timestamp
value3,timestamp
value4,timestamp
