Python doesn’t support switch-case statements. There was a proposal to introduce Python switch case statements inPEP-3103but it was rejected because it doesn’t add too much value. We can easily implement switch-case statements logic using theif-else-elif statements. However, we can implement ...

If you pass two arguments to arange(), they are interpreted as the start and stop values. Finally, you can pass all three of start, stop, and step to arange(). Notice that the order of the arguments is different from MATLAB, going start, stop, step in Python. If you’re having ...

In addition to these four operators, we also have the identity operator, denoted as ===, to check whether two values are identical to one another. Let's now consider a couple of examples of using these operators: 10 < 50 true 10 < 10 false 10 < 9 false 10 > 10 false 10 > 9 tr...
The keys of the dict are patterns, just like the "normal" dict version. The values of the dict are dicts with patterns for keys and replacements for values. The goal of this form is to enable substituting several different kinds of patterns within the limits of another one. In this exampl...
