Manipulating Files in Python

Manipulating Files in Python

The builtin open() function is used for opening files. This function returns a file object, which has methods like read() and write() associated with it, which are self-explanatory. When we are done manipulating the file, its close() method is called to close it.

# Contents of 'fileToBeReadFrom.txt'

# readingFromAFile.py
# situated in the same directory as fileToBeReadFrom.txt
fileHandler = open('fileToBeReadFrom.txt')      # or open('fileToBeReadFrom.txt', 'r')
contents = fileHandler.read()
print(contents)
fileHandler.close()
