Learn how to use Python's readlines method to read multiple lines from a file efficiently. A step-by-step guide with examples.
Read Lines To read lines and iterate through a file's contents, use aforloop: f = open("file.txt") for line in f: print(line, end="")Copy Alternatively, use thereadlines()method on the file object: f = open("file.txt")
f = open('C:myfile.txt') # opening a file lines = f.read() # reading a file print(lines) #'This is the first line. This is the second line. This is the third line.' f.close() # closing file objectAbove, f = open('C:\myfile.txt') opens the myfile.txt in the default...
