In the example above, Python executes the print statement if the condition is satisfied. However, it does not run any code if the condition is false. In this case, we can use theif-elseblock to evaluate the condition and run the else block code if the condition is not satisfied. The e...
In the body of the loop, we decrement the counter and calculate the sum of values. $ ./main.py The sum is: 104 The break statementThe break keyword is used to interrupt the cycle if needed. main.py #!/usr/bin/python import random while True: val = random.randint(1, 30) print(...
Theifstatement in Python is similar to that found in other programming languages (such as Java). It's the backbone of the logical flow of most programs. Here's an example: Python y =6ify %2==0: print('Even') The output is:
There is no switch statement in Python. You can use an if..elif..else statement to do the same thing (and in some cases, use a dictionary to do it quickly)The while StatementThe while statement allows you to repeatedly execute a block of statements as long as a condition is true. A...
In this chapter, we will learn about various flow control statements. What are the Flow Control Statements? A Flow Control Statement defines the flow of the execution of the Program. There are 7 different types of flow control statements available in Python: if-else Nested if-else for while ...

我们今天看的if,while,for都是复合语句(compound statement), 复合语句就是包含其他语句的语句,除了if,while,for还有with,try以及函数和类定义。 而在复合语句中,如果我们什么都不需要做,就可以用pass,这就像C语言中只是一个分号的空语句 一个例子,代码在这个地方等待键盘Ctrl-C来终止。
6.8 控制流语句(Control Flow Statement) 程序最小的独立单元是语句(statement),语句一般由分号结尾,缺省情况下,语句是顺序执行的,但是当涉及逻辑判断控制时,就要求有控制流程序语句。控制流程序语句分为条件语句和循环语句,在C语言中,条件语句有if、if-else、switch等,而循环过程则由while、do-while和for语句支持。
