Document Summary
Tracing the paths of where files are on the computer. Shift right click to copy as path on document/file. Text file: think as like a long string. Input/ output: associate the file with an object in the program, read and write, close the file. When we open the file in python it opens a file object. infile=open( thepathofthefilewewanttouse , r") The r here stands for read because we are opening it as a read file. We also need a file mode (read, write, or append) We open the file differently for reading then if we are going to write the file. In windows computers once we get the file path change the \ to / before opening it. Infile. read() reads all characters and returns string. Infile. readlines() outputs each line as elements in a list. Infile() important proper practice and when trying to write files in order to make the changes the file must be closed.
