How to optimize two similar but scattered code through conditional expressions?

Simplified and repeated code: cleverly use conditional expressions

In programming, it is often encountered that the logic is similar but the code is redundant due to different variables or conditions. For example, the following two code snippets:

 if d_m > d_o:
    d1 = d_m
    sf_0 = scale_factor * 0.5
    sf_1 = scale_factor
    for i in range(20):
        # ... omit if d<p> ...</p>

 if d_m  ...

The two code structures are almost the same, and only the initialization of d1 , sf_0 , sf_1 is different. We can use conditional expressions to merge the initialization parts, thereby reducing code redundancy and improving readability and maintainability.

Optimized code:

 d1, sf_0, sf_1 = (d_m, scale_factor * 0.5, scale_factor) if d_m > d_o else (d_o, 0, scale_factor * 0.5)
for i in range(20):
    # ... omit if d<p> ...</p>

Through conditional expressions, we gracefully merge the two pieces of code into one piece, maintaining logical consistency while significantly reducing the amount of code and improving the readability and maintainability of the code. This method is suitable for many similar code optimization scenarios, effectively avoiding code duplication and improving code quality.
