A survey of some other languages:
C printf: MT-Safe locale.
C++ std::cout: safe, unless you call sync_with_stdio(false).
JVM System.out.println: safe in common JVMs.
C# Console.WriteLine: safe.
Go fmt.Printf: safe.
Rust println!: safe.
Ruby puts: safe.
So it seems that Python is the outlier here.
- vitaut 3y agostd::cout is thread-safe but because of the concatenation-based API parts of the message may interleave. C++23 std::print is safe (and the output doesn't interleave). See https://vitaut.net/posts/2023/print-in-cpp23/ https://vitaut.net/posts/2023/print-in-cpp23/.
