built for developersReal code typing practice. Useful metrics. Improve faster.Learn more
Codestroke is a code typing test for developers. Practice real JavaScript, Python, SQL, Java, C++, HTML/CSS, PHP, Go, and Kotlin snippets instead of ordinary prose.
This Python typing test focuses on list comprehensions, decorators, and dataclasses. Choose a 30, 60, or 120 second session and track your code typing speed and accuracy as you practice.
Python code typing practice
Practice a Python typing test with realistic snippets that use list comprehensions, decorators, dataclasses, and indentation. The sessions build Python code typing fluency through accurate punctuation and structure.
Try the main code typing test or choose another language from the directory below.
Useful metrics
Track live CPM, accuracy, time, and detailed session results.
Flexible practice
Choose a 30, 60, or 120 second test and improve at your pace.
how speed and accuracy work
Code typing speed is measured in CPM (characters per minute), so symbols, brackets, and indentation count just like letters. Accuracy shows how much of the snippet you entered correctly. Pick a language to practice a focused code typing test:
code typing test FAQ
What does the Python typing test include?
The Python test uses realistic snippets with common Python syntax such as functions, list comprehensions, decorators, dataclasses, and indentation.
What is a code typing test?
A code typing test measures how quickly and accurately you can type real source code instead of ordinary prose. Codestroke is built for developers.
How does a coding speed test work?
Code contains symbols, brackets, and short tokens, so CPM measures every typed character. Codestroke also reports WPM, accuracy, and the selected test duration.
Why measure CPM instead of WPM?
Words per minute can be misleading for code because syntax contains punctuation and short tokens. CPM gives a clearer view of code typing speed.
Which languages can I practice?
You can practice JavaScript, Python, SQL, Java, C++, HTML/CSS, PHP, Go, and Kotlin snippets.
Is Codestroke free?
Yes. The typing test is free in modern web browsers, and you can begin as a guest without creating an account.
