Is Python good for CP? ›

Oftentimes, programmers wonder if knowledge in Python programming is enough to help them ace competitive coding. The answer is a resounding "yes!".

Since Python is a dynamically typed language, which means that it doesn't know about the type of the variable until the code is run, it is incredibly flexible and enables us to use modular components created in other programming languages. For example, you could import a C++ program as a module into Python.

The reason that everyone calls Python slow is because of the primary implementation, CPython. CPython is interpreted, meaning that you load a text file into it and it will try to convert that into a sequence of actions to run, but it only does so one step at a time.

Yes, python is slow for cp. Switch to c++ asap. Also note that getting tle probably means ur algorithm was not optimized. Since most of the judges uses multipliers.

C++ is the most preferred language for competitive programming mainly because of its STL.

C++ and Java are the best languages for competitive programming. Most competitive programmers participate using C/C++. Java is the second most popular language for competitive programming.

Python is a high-level programming language: The code of Python looks very similar to how humans think. For that reason, it must Separate the details of the computer from you: memory management, pointers,… Hence, it is slower than “lower-level language” like C.

Unlike C++ or Java, Python's standard interpreter, CPython, executes bytecode in a straightforward manner without the extensive optimizations seen in compiled languages or the JVM. This loop iterates and executes each step line-by-line, leading to typically slower execution.

Why can't Python be faster? ›

C and C++ do a complex compilation process to turn the source code into machine code that runs directly on the processor. Python does a simple compilation process that turns source code into tokens, and the Python interpreter steps through the tokens. Python will always be much slower.

It is said that python is 100 times slower than C.

If you're looking for a general answer, here it is: If you just want to learn the Python basics, it may only take a few weeks. However, if you're pursuing a career as a programmer or data scientist, you can expect it to take four to twelve months to learn enough advanced Python to be job-ready.

C++ duel lacks a clear winner, as the better choice depends on individual preferences and project requirements. Python excels in quick learning and the rapid development of small programs. In contrast, C++ is suitable for large projects and exploring multiple languages, although it requires more time to master.

C might run something in a few nanoseconds, and Python will be 1000x slower, and run it in a few milliseconds. Is that really going to have a major impact? Unless you are running this calculation millions of times, likely not. So don't worry about using Python even though it is slower than C.

Implementation of the functionality of copy (cp) command in python. We are be able to copy files we are able to copy directories using a similar -r option, we are able to copy files forcefully using -f option and do not use any predefined libs that do the same like shutil, subprocess, etc. linuxcp. import os.

Speed : C++ is much more faster than Python. But, there is a time multiplier for Python in most of the judges. But if speed is the main concern go with c++. Lines of code : In this case, Python wins.

Python is commonly used for developing websites and software, task automation, data analysis, and data visualisation. Since it's relatively easy to learn, Python has been adopted by many non-programmers, such as accountants and scientists, for a variety of everyday tasks, like organising finances.

One of the major drawbacks of this language is that its design has numerous issues. Python programmers face several issues regarding the design of the language. This language requires more testing and also it has errors that only show up at runtime this is because the language is dynamically typed.
