This article mainly introduces python how to achieve ternary expressions, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

Ternary expression

In many use cases, we need to define variables with specific values based on conditions, and we can simply use if. Else statement to check the condition. However, it takes several lines of code. If you deal with the assignment of only one variable, you may need to use a ternary expression that checks the condition and completes the assignment in just one line of code. In addition, its format is shorter, making the code more concise. Consider the following example.

# The typical way if score > 90: reward = "1000 dollars" else: reward = "1000 dollars" # Do this instead reward = "1000 dollars" if score > 90 else "500 dollars"

Sometimes we can get some data from a defined function, and we can take advantage of this and write a simple operation of a ternary expression, as shown below.

# Another possible scenario # You got a reward amount from somewhere else, but don't know if None/0 or not reward = reward_known or "500dollars" # The above line of code is equivalent to below reward = reward_known if reward_known else "500dollars" Thank you for reading this article carefully. I hope the article "how to implement ternary expressions in python" shared by the editor will be helpful to you. At the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
