Is there any easy method with python for reading and adding a new line for all the files in a folder when condition met.
I have 2 files ABC.TXT and DEF.TXT with the below content.
AAAAAA* TEST * BBBBBB*===================== CCC1QR RAQWERT BBBBBB*===================== RBBBBB ===================== MBBBBB ===================== DEF.TXT RRR AA* TEST * QWRRAB*===================== CCC1QR 123QWE BBBBBB*===================== JBBBBB ===================== RBBBBB =====================
When there is a space in the 7 th position of a line, I need add 2 lines(starting at position 8) and rewrite the files as is. The new lines to be added only once when it finds the space first time on the file at position 7. ABC.TXT
AAAAAA* TEST * BBBBBB*===================== CCC1QR RAQWERT here is my line1 here is my line2 BBBBBB*===================== RBBBBB ===================== MBBBBB =====================
RRR AA* TEST QWRRAB*===================== CCC1QR 123QWE line1 added after first find of space line2 added after first find of space BBBBBB*===================== JBBBBB ===================== RBBBBB =====================
This is the code. The comments along the way will explain the code
files = ["ABC.txt","DEF.txt"] for file in files: #Looping through all the files f = open("ABC.txt", "r") para = f.read() spaceDetected = False #To ensure we add lines only one time newPara = "" for line in f.read(): if line == " " and spaceDetected == false: # Checking if the letter at index 6, which is the 7th letter is a space and the 2 lines have not been added yet newPara += line + " This is my line 1n This is my line 2n"#You may need to remove the newline from end and add one to the start else: newPara += line w = file.open(file,"w") w.write(newPara)
This should sort through all the files and do what you want. Though this does look like you school project, I had some free time
