从文件夹导入文本文件

Question

I am using Python 3.7. I have hundreds text files containing stock price data in a parent folder. I want extract only the closing price column of each text file. Is there a way to extract only one column of each text file from the parent folder?

Answer 1

I'm guessing you want to extract a specific line from a text file? If so then here's your answer.

File = open('File_Name.txt')
Lines = File.readlines()
print(Lines[Choose])

Choose means what ever line you want to print out. FYI 0 is the starting line so if you replace "Choose" with 0 you will print the first line written inside that text file.
