# ] Reading ZIP files > import zipfile, os Since these methods return list-like values instead of true lists, you should pass them to the list() function to get them in list form. Just like dictionaries, shelf values have keys() and values() methods that will return list-like values of the keys and values in the shelf. To open and read variables: > with shelve. > print (content ) # Hello world! # Bacon is not a vegetable. # 25 > with open ( 'bacon.txt' ) as bacon_file. # 13 > with open ( 'bacon.txt', 'a' ) as bacon_file. # When, in disgrace with fortune and men's eyes, # I all alone beweep my outcast state, # And trouble deaf heaven with my bootless cries, # And look upon myself and curse my fate, Writing to files > with open ( 'bacon.txt', 'w' ) as bacon_file. You can also iterate through the file line by line: > with open ( 'sonnet29.txt' ) as sonnet_file. > hello_contentĪlternatively, you can use the readlines() method to get a list of string values from the file, one string for each line of text: > with open ( 'sonnet29.txt' ) as sonnet_file. Opening and reading files with the open() function > with open ( 'C:\\Users\\your_home_folder\\hi.txt' ) as hello_file. To read/write to a file in Python, you will want to use the with statement, which will close the file for you after you are done, managing the available resources for you. readlines ( 300 ) ) # closing the fileįile's content (using readlines() method).Reading and Writing Files The file Reading/Writing process readlines ( 10 ) ) # reads next 300 bytes, if no more bytes # method will not read more bytes print ( "myfile1.readlines(300)." ) print (myfile1. seek ( 0 ) # reads only 10 bytes print ( "myfile1.readlines(10)." ) print (myfile1. readlines ( ) ) # reading a total number of bytes # seeking file's position to 0th position Myfile1 = open ( "hello1.txt", "r" ) # reading and printing the file's content # using readlines() print ( "file's content (using readlines() method)." ) print ( "myfile1.readlines()." ) print (myfile1. close ( ) # reading the file (opening file in 'r' mode) write ( "Menaka, 17, Indraloka \n " ) # closing the file Myfile1 = open ( "hello1.txt", "w" ) # writing content in the file The return type of this method is, it returns the lines in the form of a list.Įxample: # Python File readlines() Method with Example # creating a file If the len is greater than the total number of bytes of the file, then no more content will return. It's default value is -1 that specifies all lines. len – It is an optional parameter and it can be used to specify the total number of bytes to read from the file.Readlines() method is an inbuilt method in Python, it is used to get all lines from the file, the method is called with this object (current file stream/IO object) and returns all available lines in the file, we can also specify the total number of bytes to read from the line.
