Preprocessor commands are very powerful and are used extensively during programming, such as easy to use in version release, 1, #define (tells the compiler that there is a symbol for the given name) #undefine (delete symbol) 2,

Conditional judgment can be divided into:Single-branch judgment: only one if statementTwo-branch judgment: if Else's formatMulti-Branch judgment: if elif else formatConditional statement nesting judgment#Here's a conditional multi-branch judgment

In the shell of Linux The IF statement determines which branch to execute through the relational operator to determine the true or false of an expression. The Shell has three kinds of if ... else statements: If ... fi statement; if ... else .

This article describes in detail three options in Python: If statements, if/else statements, and if/Elif/else statements. For each statement, we provide the corresponding flowchart. At the same time, we provide many simple sample programs to help

When programming, you often need to check a set of conditions and decide what action to take accordingly. In Python, the IF statement allows us to examine the current state of the program and take appropriate action accordingly. 5.1 A simple
