Working with Files in Python

Creating an Empty File

open(pathtofile, 'w').close()

Writing to a File

pathtofile = 'oneline.txt'
txt = "A line of text";
thefile = open(pathtofile, 'w') # 'w' opens a file for overwriting. 
thefile.write(txt)
thefile.close()

pathtofile = 'twolines.txt'
txt = "Two lines of text.\nThe End.";
thefile = open(pathtofile, 'w')
thefile.write(txt)
thefile.close()

pathtofile = 'manylines.txt'
thefile = open(pathtofile, 'w')
thefile.write("Many lines of text,\n")
thefile.write("May be easier to deal with,\n")
thefile.write("By calling write() multiple times.\n")
thefile.close()

Append to a File

pathtofile = "manylines.txt"
thefile = open(pathtofile, 'a') # 'a' opens the file for appending.
thefile.write("\n\n")
thefile.write("But is it really the end?\n\n")
thefile.write("Yes, Howard.")
thefile.close()
