如何修改文本文件的内容？

Question

I have a text file contains the following data

Repetition,4213-RTN-01-8 Counts BER,Microwave,Huawei-RTN-Alarms,Packet Drop,2938,Normal,Regional Operations,,,

and I just need to replace , with ,,

My code is

x=open("D:\Work\Robotics\RTN Sheets\pandas.txt","r+")  #open the file with read/write previlage
x.read().replace(",",",,").write() #read the contents and apply the replace action

Then I couldn't find a proper way to add this modification for the Text file.

Answer 1

You are trying to call .write() method on the string.

Change your second line to x.write(x.read().replace(",",",,")) and also add x.close() at the end.

Hope this helps!

Answer 2

You should perform a file seek to reset the file pointer to 0 after you read the file so that the file content can be replaced rather than appended:

with open("D:\Work\Robotics\RTN Sheets\pandas.txt", "r+") as file:
    content = file.read()
    file.seek(0)
    file.write(content.replace(',', ',,'))

Answer 3

change your code to this:

x = open("text.txt", "r")
a = x.read().replace(",", ",,")
x.close()
x = open("text.txt","w")
x.close()
