如何读取连续的.plt文件并将其存储 [英] How to read consecutive .plt files and store them

问题描述

我有1000个要使用python读取的文件.以前，我只有74岁，我只是一个一个地阅读它们，但是现在要做的太多了.

I have 1000 files that I want to read with python. Before, I had 74 and I just read them one by one, but now there are too much to do so.

data_1 = np.genfromtxt('test4-1.000001.plt', delimiter=' ', skip_header=3)
data_2 = np.genfromtxt('test4-1.000002.plt', delimiter=' ', skip_header=3)         
data_3 = np.genfromtxt('test4-1.000003.plt', delimiter=' ', skip_header=3)         
data_4 = np.genfromtxt('test4-1.000004.plt', delimiter=' ', skip_header=3)         
data_5 = np.genfromtxt('test4-1.000005.plt', delimiter=' ', skip_header=3)         
data_6 = np.genfromtxt('test4-1.000006.plt', delimiter=' ', skip_header=3)         
data_7 = np.genfromtxt('test4-1.000007.plt', delimiter=' ', skip_header=3) 
.
.

data_73 = np.genfromtxt('test4-1.000073.plt', delimiter=' ', skip_header=3)
data_74 = np.genfromtxt('test4-1.000074.plt', delimiter=' ', skip_header=3)

我尝试使用循环，但是没有用.我试图使自己成为弦乐，但仍然无法正常工作

I have tried to use a loop for, but it doesn't work. I tried to make i be a string, but still didn't work

for i in range(1:1000):
     data_'i' = np.genfromtxt('test4-1.00000'i'.plt', delimiter=' ',skip_header=3)

非常感谢您的帮助

推荐答案

您虽然有一个正确的主意，但是您犯了一些语法错误，而且您似乎需要了解列表.

You kinda have the right idea but you made a few syntax mistakes, and it looks like you need to learn about lists.

您应该做的是列出所有数据.让我们称之为 data .

What you should do is make a list of all your data. Lets call it data.

我们这样定义一个空: data = []

We define an empty like like this: data = []

要添加到列表中，我们使用如下的append命令:

To add to a list we use the append command like this:

data.append(np.genfromtxt('test4-1.000001.plt', delimiter=' ',skip_header=3))

最后一件事是您试图错误地连接字符串.在python中，您使用 + 连接字符串，因此以下行:'test4-1.00000'i'.plt'应该为'test4-1.'+ str(i).zfill(6)+'.plt'.请注意，我必须首先将其转换为字符串，并且还使用了 zfill 函数将其填充为零.

The last thing is you were trying to concatenate your strings wrong. In python you concatenate strings with a + so this line: 'test4-1.00000'i'.plt' should be 'test4-1.'+str(i).zfill(6)+'.plt'. Note I had to turn it into a string first and I also used the zfill function to pad it with zeros.

将所有这些放在一起，我们就有了代码

Putting all this together we have the code

data = []
for i in range(1:1000):
    data.append(np.genfromtxt('test4-1.'+str(i).zfill(6)+'.plt', delimiter=' ',skip_header=3))

这将为您提供一系列数据，您可以使用语法 data [23] 调用这些数据以获取第24个数据集(列表索引从0开始).

This will leave you with a list of data that you can call from using the syntax data[23] to get the 24th data set (list indexing starts at 0).

希望这对您有帮助！
