The book, Programming Python, shows an example of os.chdir() on the

Otherwise the \t ( Tab ) will be inserted in the string:
print a\tb

Let's see if I can get this right.as I am working on memory and not enough

The 'r' means that using a raw string so the backslashes aren't escaped

The equivalent without using the 'r' would be: os.chdir('c:\\temp')

Thank you all for the enthusiastic responses. It must have been other

also realized that "file" is a poor choice of variable name. Thanks
