I will try my first post, on the advice of a respected Python teacher - I am busy writing something every day.. I recently started learning this language, motivating myself that knowledge of Python development will help me on the way to victory. . and after it, definitely. The prospects are obvious and do not require extra thinking.. so, I think this is a good start to the New Year 2025...
And so, what today? Another lecture on Python development was held, at which we quickly ran through the dictionaries and began to study functions..
[print(i) for i in letters]
List Comprehension construct, interesting - I was asking if its result can be assigned to a variable? They say it is possible. Let's check.
There are 1.5 days left until the next lecture, and it would be desirable to learn the material of 2 more lessons and make a DZ on them..
The above is the detailed content of Study prospects... For more information, please follow other related articles on the PHP Chinese website!

How do you slice a Python array?May 01, 2025 am 12:18 AMThe basic syntax for Python list slicing is list[start:stop:step]. 1.start is the first element index included, 2.stop is the first element index excluded, and 3.step determines the step size between elements. Slices are not only used to extract data, but also to modify and invert lists.
