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'
Python is an extremely versatile language.
It is not limited to desktop applications or applications on the web.
People who code in Python are often referred to as "Pythonistas" or "Pythoneers ".
# 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()
