Previous: http://www.bkjia.com/kf/201206/136910.htmlWe are moving from simply inputting exercises to learning the real work of code. We need to do more exercises. The exercises below are long, so are your patience and the exercises in the next

In previous exercises, we have been printing and calling functions, and all programs are executed in the top-down mode. If you write a function, you need to select which branch to execute during execution. Now we can use if, else, And elif to

This method is read until the EOF uses readline () to return a list containing rows. If the optional sizehint parameter exists, instead of reading to EOF, the entire row is approximately sizehint bytes read (possibly rounded to the size of the

Python can be used for fast programming. It can be nested into other languages (such as c/c ++) to improve programming efficiency. Currently, almost all of the online embedding python in c ++ is nonsense, and it has not been available for a long

There are several parameters in Python functions. One is location-based parameters, and the other is location-based parameters that are assigned values based on variable names are saved to tuples by * args, parameters assigned based on variable

A regular expression (regular exprssion) is a text match pattern described by a formal syntax. The mode is interpreted as a group of commands, and then the group of commands is executed. Use a string as the input to generate a matching subset or a
