我正在使用的当前代码无法将我的文本替换为 .txt 文件中的其他文本，我该如何用 Python 替换它？

Question

Currently using this code

f1 = open('C:\Users\folderName\Python Tests\data.txt', 'r')

f2 = open('C:\Users\folderName\Python Tests\data.txt', 'w')

for line in f1:

        f2.write(line.replace('pyton', 'python'))

f1.close()

f2.close()

Im using Jupyter Lab and Python 3.7.5 64-bit

any help?

The issue at matter is actually for a MUCH bigger file that lives on my local computer, I have a notepad file that has about a million lines of information.

What i really need is to replace " " with "|"

But im looking to automate this, instead of going in the file and hitting CTLR + H everytime

thanks guys

Here is how you can easily read and replace specific word/letter/space etc from file with another text/space.

f1 = open("data.txt", "r")
text = f1.read();
f1.close()

f2 = open("data.txt", "w")
text = text.replace(" ","|")
f2.write(text);
f2.close()
