# CSDN vs Изучаем Python

The clearest difference is ads: Изучаем Python at none against CSDN's shown. Изучаем Python also leads on review sentiment (67% vs 45%). CSDN's advantage is update cadence (weekly vs every 3 weeks) and chart position (#118 vs unranked). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. CSDN sells 15 in-app purchases, starting at $12.99 per month and Изучаем Python sells 4 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for CSDN against 4.7 for Изучаем Python. That said, the two scores are not equally well evidenced: CSDN has 1.7K ratings behind it against 257, so its average is the more settled of the two. Written reviews are what separate them: 45% of CSDN's written reviews are positive against 67% of Изучаем Python's.

CSDN ships an update weekly, Изучаем Python every 3 weeks. The most recent releases landed on September 28, 2026 and September 24, 2026 respectively.
