Writing integer to file

[Larz60+]

You open the file as mode 'a' which means append.
It will create the file if it doesn't exist, but if it does exist, it will retain contents and append new contents.
you should open as mode 'w' if you don't want this.

def write_file(filename, intval):
    with open(filename, 'w') as fp:
        print(f'intval: {intval}')
        fp.write(str(intval))

def read_file(filename):
    with open(filename) as fp:
        return fp.read()

if __name__ == '__main__':
    myfile = 'tryit.txt'
    CurrentCount = 300
    write_file(myfile, CurrentCount)
    print(f'reading result: {read_file(myfile)}')

output:

Output:
intval: 300
reading result: 300

hexdump:

Output:
$ hd tryit.txt
00000000  33 30 30
00000003
