如何读取Python中的文本文件编号的数组 [英] how to read array of numbers from text file in python

问题描述

我已经写了code为：

 阵列= [[1.630217208498539]，[0.019929319226538452]
FO =打开（file.txt的，W）
fo.write（STR（阵列））
fo.close（）
 

这将保存.txt文件的阵列，在.txt文件内容是二维数组：

[1.630217208498539]，[0.019929319226538452]]

和我想这个数组，因为它是返回到另一个程序，这样我可以使用这个数组用于进一步计算（读阵列不应该是一个字符串）

解决方案

 进口泡菜 numlist = [[1.630217208498539]，[0.019929319226538452] OUTFILE =打开（log.txt的，WB） 和pickle.dump（numlist，OUTFILE） outfile.close（） INFILE =打开（log.txt的，RB） 和pickle.load（INFILE）
 [1.630217208498539]，[0.019929319226538452]
 

I have written code as:

array = [[1.630217208498539], [0.019929319226538452]] 
fo = open("file.txt", "w")
fo.write(str(array))
fo.close()

That will save the array in .txt file, the content in the .txt file is in 2d array as:

[[1.630217208498539], [0.019929319226538452]]

And I want this array as it is back to the another program so that i can use this array for further calculation (the read array should not be a string)

解决方案

 import pickle

 numlist = [[1.630217208498539], [0.019929319226538452]] 

 outfile = open("log.txt", "wb")

 pickle.dump(numlist, outfile)

 outfile.close()

 infile = open("log.txt", "rb")

 pickle.load(infile)
 [[1.630217208498539], [0.019929319226538452]]
