In the above example, the elif conditions are applied after the if condition. Python will evalute the if condition and if it evaluates to False then it will evalute the elif blocks and execute the elif block whose expression evaluates to True. If multiple elif conditions become True, then ...
Before we wrap up, let’s put your knowledge of Python if else to the test! Can you solve the following challenge? Challenge: Write a function to check whether a student passed or failed his/her examination. Assume the pass marks to be50. ReturnPassedif the student scored more than 50....

Python 中的 for 语句与你在 C 或 Pascal 中所用到的有所不同。 Python 中的 for 语句并不总是对算术递增的数值进行迭代(如同 Pascal),或是给予用户定义迭代步骤和暂停条件的能力(如同 C),而是对任意序列进行迭代(例如列表或字符串),条目的迭代顺序与它们在序列中出现的顺序一致。 例如(此处英文为双关语):...

It can also be the return value from a function. Any expression that evaluates to a Boolean value of True or False is permitted. A simple Python if statement looks like this: if boolean_expression: command When the Python interpreter encounters the if keyword, it evaluates the boolean_...
Just like case(i ), we can put the function name in place of the case. With the same intentions, we will get the following output: And hence, you can use the switch statement with some minor tweaks. This was just to widen your knowledge spectrum in Python andis not a part of the ...
