This gives you a way to include statements in your Python files that are executed only when the module is run or, conversely, only when it is imported. The comparison of __name__ to '__main__' would almost always be done in a conditional statement and placed at the end of the file...
4.2. for Statements(for语句) The for statement in Python differs a bit from what you may be used to in C or Pascal. Rather than always iterating over an arithmetic progression of numbers (like in Pascal), or giving the user the ability to define both the iteration step and halting condi...
It is a much more advanced construct than the if/else statements. Pattern matching has a complex syntax and is covered in a Python pattern match. main.py #!/usr/bin/python grades = ['A', 'B', 'C', 'D', 'E', 'F', 'FX'] for grade in grades: match grade: case 'A' | '...
statements(s) 1. 2. 举个样例来看。 ProLan=['C','CPP','JAVA','PYTHON'] for item in ProLan: print item 1. 2. 3. 这样输出的结果是: C CPP JAVA PYTHON 1. 2. 3. 4. 假设不想换行。那么就在item后增加" ," 即 ProLan=['C','CPP','JAVA','PYTHON'] ...
As you might have guessed, this is achieved using control flow statements. There are three control flow statements in Python - if, for and while.The if statementThe if statement is used to check a condition: if the condition is true, we run a block of statements (called the if-block),...
Now, let's take a look atifstatements. The if statement 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:
As mentioned, these two characteristics are required in Python for flow control statements. 正如所提到的,这两个特征是Python中流控制语句所必需的。 www-128.ibm.com 7. It should because flow control statements are compound statements. 当然应该类似,因为流控制语句就是复合语句。 www.ibm.com 8. A ...

In this chapter we are going to look at the if statement in Python. This statement is used to control the flow of execution within a program based on some condition. These conditions represent some choice point that will be evaluated to True or False . To perform this evaluation it is ...
