In this chapter, we learned about standard input and output. We learned how stdin and stdout act as keyboard input and user's Terminal respectively. We also learned about input() and print() functions. In addition to this, we learned about sending an email from Gmail to the receivers. We sent an email with simple text and also sent an attachment. Also, we learned about string formatting using the format() method and the % operator.
