does not print into the original file

Question

in the last 2 lines the file1 stays blanks even with the write function. the rest of the code works flawlessly

def modQuantity(filepath: str,):
    model = input("Model: ")
    size = input("size")
    newquantity = input("New Quantity: ")
    file = open(filepath, 'r')
    tempfile = open(filepath+"temp", 'w')
    for line in file:
        sep = line.split()
        if sep[0] == model and sep[1] == size:
            tempfile.write(f"{sep[0]} {sep[1]} {newquantity}n")
        else:
            tempfile.write(f"{line}")
    tempfile.close()
    file.close()
    tempfile1 = open(filepath+"temp", 'r')
    file1 = open(filepath, 'w')
    for line1 in tempfile1:
        file1.write(f"{line1}")

Answer 1

You didn’t close the file so it hadn’t chance to flush the content. You can use that method by yourself or close the file.

I recommend to use contextmanager so you can be sure file is flushed and closed:

    with open(filepath, 'w') as file1:
        for line1 in tempfile1:
            file1.write(f"{line1}")
