how to read a text file line by line in python
# Open the file with read only permit
f = open('my_text_file.txt')
# use readline() to read the first line
line = f.readline()
# use the read line to read further.
# If the file is not empty keep reading one line
# at a time, till the file is empty
while line:
# in python 2+
# print line
# in python 3 print is a builtin function, so
print(line)
# use realine() to read next line
line = f.readline()
f.close()
# Python code to
# demonstrate readlines()
L = ["Geeks\n", "for\n", "Geeks\n"]
# writing to file
file1 = open('myfile.txt', 'w')
file1.writelines(L)
file1.close()
# Using readlines()
file1 = open('myfile.txt', 'r')
Lines = file1.readlines()
count = 0
# Strips the newline character
for line in Lines:
print("Line{}: {}".format(count, line.strip()))
