Modifying a date format

[jehoshua]

As I had 10 mins spare, I've come up with a possible solution:

Thanks, I added a loop to read the file, code now ..

def format_date(date):
    for index, item in enumerate(date):
        if index == 0:
            month = item.lstrip("D")
            month = "D" + str(f"{int(month):02d}")
        elif index == 1:
            day = str(f"{int(item):02d}")
        else:
            year = item.rstrip("\n")

    return f"{month}/{day}/{year}"

f = open("ANCU.qif","r")
lines = f.readlines()

for line in lines:
    if line[0] == 'D':
        date = format_date(line)
    continue

print(date)

# closing the file
f.close()

Output:
Traceback (most recent call last):
  File "......search_replace_5.py", line 18, in <module>
    date = format_date(line)
  File ".....search_replace_5.py", line 5, in format_date
    month = "D" + str(f"{int(month):02d}")
ValueError: invalid literal for int() with base 10: ''
