read line python code example
Example 1: python read file line by line
with open("file.txt") as file_in:
lines = []
for line in file_in:
lines.append(line)
Example 2: python read file line by line
file1 = open('myfile.txt', 'r')
Lines = file1.readlines()
# usage:
count = 0
for line in Lines:
count += 1
print("Line{}: {}".format(count, line.strip()))
Example 3: 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()
Example 4: python read lines
f = open("filename")
lines = f.readlines()
Example 5: Readline Python
f = open("C:\\Users\\Andreea Pantus\\Desktop\\An 2, Semestrul 2\\Inteligenta artificiala, machine learning\\ai-unibuc-24-22-2021\\train.txt", "r")
print(f.readline())
Example 6: read line of a file in python
file1 = open('myfile.txt', 'r')#open the file (mode read)
count = 0 #used to count the lines
for line in Lines:
line = file1.readline()#read a single line
if not line:
break
count += 1
print("Line{}: {}".format(count, line))#print the lines with their number
