Understanding the ternary operator in Python [duplicate]

Question

I'm currently transitioning from JavaScript to Python, and I'm wondering if Python has a ternary operator similar to JavaScript.

In JavaScript, I would write a ternary operation like this:

let a = 10;
let value = a > 5 ? 'Greater' : 'Lesser';
console.log(value); // 输出：'Greater'

This is very convenient for writing compact conditional code. I'm trying to figure out if there is an equivalent method in Python? If so, how can I rewrite the above JavaScript snippet in Python?

I tried searching for "Python ternary operator" but the results I got were not very clear, especially when compared to JavaScript.

If it exists, can someone provide a simple explanation and some examples of how to use the ternary operator in Python?

I expect a smooth transition.

The syntax in Python is slightly different, they are called Conditional expressions:

[value_if_true] if [expression] else [value_if_false]

Here is your Python example:

a = 10
value = 'Greater' if a > 5 else 'Lesser'
print(value); # 输出：'Greater'
