I learnt Python in the first year of my college and since then it has become my go-to language for everything. Whenever I have to try out any algorithms or anything else, Python is always my first choice. People sometimes wonder why do I prefer Python over C++/Java so much.
- In-built basic data-structures which are very easy to expand.
- The open-source spirit in the Python community is very strong.
- It's very easy for a beginner to pick-up Python instead of C/C++ or Java. It even reads like pseudocode.
- Indentations. Although, most of my friends in college don't like to indent their code manually, Python's indentation restrictions has made me so much habitual of indented code that I personally make it point to indent all code I get from anyone. (Text editors help a lot, too)
- PEP - Although they seem as annoying at first, but IMHO it makes the code look very elegant and beautiful. (The apt word would be: readable, of course)
- The performance-hit compared to Java or C++ is every penny-worth of the simplicity and awesomeness of Python. When you really need to use all CPU cycles for your time-critical applications, you can always embed C in your scripts.
- Prototyping is done best in Python. Period.
To the C++ purists: Performance of a programming language should not be the time taken between launching a program and completion of the execution. To me, it is the time since we decide to write a program till the time we become satisfied with what we have written. This is where Python fares above all other languages.
