- ‘a’ – append mode.
- ‘rb’ – reading mode in binary.
- ‘r+’ – reading mode plus writing mode at the same time.
- ‘rb+’ – reading and writing mode in binary.
- ‘wb’ – writing mode in binary.
- ‘w+’ – writing and reading mode.
What is the difference between open and with open in Python?
Within the block of code opened by “with”, our file is open, and can be read from freely. However, once Python exits from the “with” block, the file is automatically closed. Thus, by using “with”, you avoid the need to explicitly close files.
What are the most common modes used when opening a file?

The second parameter of the open () function is the mode, a string with one character. That single character basically tells Python what you are planning to do with the file in your program.
