Python 3.7 vs Python 3.9

Developers should learn Python 3 meets developers should learn python 3. Here's our take.

Python 3.7

Nice Pick

Developers should learn Python 3

Pros

• 7 for its modern features that simplify code, such as data classes for structured data and improved async/await support, making it ideal for applications in data analysis, machine learning, and backend services
• Related to: python, data-classes

Cons

• Specific tradeoffs depend on your use case

Python 3.9

Developers should learn Python 3

Pros

• 9 for its modern syntax features, such as the merge (|) and update (|=) operators for dictionaries, which simplify data manipulation tasks
• Related to: python, type-hinting

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Python 3.7 if: You want 7 for its modern features that simplify code, such as data classes for structured data and improved async/await support, making it ideal for applications in data analysis, machine learning, and backend services and can live with specific tradeoffs depend on your use case.

Use Python 3.9 if: You prioritize 9 for its modern syntax features, such as the merge (|) and update (|=) operators for dictionaries, which simplify data manipulation tasks over what Python 3.7 offers.

The Bottom Line

Python 3.7 wins

Developers should learn Python 3
