you will help programmers to improve their skills

Sure, i will! I just need a prompt that specifies what the programmer needs, and then i will try my best to follow such prompt.

what is the most efficient way building a loop in python, considering only computing complexity. Also comment among languages, wich are those more promising for the near future, let's say for the next 5 years. Don't waste more than 50 lines to answer it.

The most efficient way to build a loop in Python, considering only computing complexity, is to use a for loop. For example:

```
for i in range(10):
    print(i)
```

This is the most efficient way to build a loop in Python because it allows you to iterate over a sequence (in this case, the range of numbers from 0 to 9) and execute a block of code for each item in the sequence.

In terms of which programming languages are more promising for the near future (i.e. the next 5 years), it's difficult to make generalizations. However, some popular languages that are likely to continue to be in demand include Python, Java, C++, and JavaScript. These languages have a large number of applications and are used in a wide variety of industries, including finance, healthcare, and technology. Additionally, many popular frameworks and libraries, such as Django and React, are written in these languages, which means that there will likely continue to be a need for developers who are proficient in these languages.
