I'm trying to get rid of/remove/delete strings of the months that do not contain the letter "r" from a file, but it is not executing correctly.

Here's my code:

def main():

# Displays the name of the months, but months that do not contain the letter

# r are automatically deleted from the txt file.

file = "SomeMonths.txt"

infile = open(file, 'r')

line = infile.readline()

while line != "r":

print(line, end="")

line = infile.readline()

infile.close()

main()

Output:

January

February

March

April

May

June

July

August

September

October

November

December
