How many lines will the loop in the following code read if the file 'in.txt' contains 10 lines? How
many if it contains 7 lines?
f = open('in.txt')
line = f.readline()
counter = 0
while line!= .
line =
f.readline()
print(line)
3 f,readline()
line =
print(line)
counter+=2
f.close()
a. 9 and 6 lines, respectively.
b. 10 and 7 lines, respectively.
c. 2 and no lines, respectively.
d. The loop is infinite, so it reads the whole file except the first line; so 9 and 6 lines, respectively.
e. The file exhaustively read before the loop, so the loop does not read any lines at all.
