我从不同线程读取/写入pandas数据帧是否安全？

Question

My code is quite simple. I have two thread scraping two webpages, filling two dataframes, and then writing two different files.

module1.py
df1.to_csv(f1)
df2.to_csv(f2)

And I have a different python process who read those two files.

module2.py
df3 = pd.read_csv(f1)
df4 = pd.read_csv(f2)

Is this thread-safe ?

Answer 1

我认为除非代码并行运行，否则您不必担心线程安全。
