Writing to a text file, last entry is missing

February 7, 2023

This code calls no errors, but my text file is not getting betty and her grade. It’s only getting the first three out of the four combinations. What am I doing wrong? Thanks!

students = ['fred','wilma','barney','betty']
grades = [100,75,80,90]
for i in range(4):
    file = open("grades3.txt", "a")
    entry = students[i] + "-" + str(grades[i]) + '\n'
    file.write(entry)
file.close

>Solution :

You should use use with open() as ... to automatically open, close and assign the file handle to a variable:

students = ['fred','wilma','barney','betty']
grades = [100,75,80,90]
with open("grades3.txt", "a") as file:
    for i in range(4):
        entry = students[i] + "-" + str(grades[i]) + '\n'
        file.write(entry)
