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 con
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 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:
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 ...

For example, it is possible to wait with the continuation of the workflow until a file appears on a cloud storage or an SQL statement provides a valid result. 例如,可以等待工作流的继续,直到文件出现在云存储上或 SQL 语句提供有效结果。 Advanced functions, such as the reuse of workflow parts ...

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。
