low_memory : bool, default True Internally process the file in chunks, resulting in lower memory use while parsing, but possibly mixed type inference. To ensure no mixed types either set False, or specify the type with the dtype parameter. Note that the entire file is read into a single D...
This can make their processing extremely slow or even prevent you from fitting the entire file into memory at once. In this part of the tutorial, you’ll read a relatively big WAV file in chunks using lazy evaluation to improve memory use efficiency. Additionally, you’ll write a continuous...

Consider the following code, which performs regular Python file I/O: Python def regular_io(filename): with open(filename, mode="r", encoding="utf8") as file_obj: text = file_obj.read() print(text) This code reads the entire file into physical memory, if there’s enough available...

Traverse the information in the startup_info file and read the *EFFECTIVE_MODE field. If it has been set, no processing is required. If it is set to None, the default activation mode is used based on the file type. The system software package and configuration file take effect only ...

The entire Python program exits when no alive non-daemon threads are left. python 对于 thread 的管理中有两个函数:join 和 setDaemon join:如在一个线程B中调用threadA.join(),则 threadA 结束后,线程B才会接着 threadA.join() 往后运行。 setDaemon:主线程A 启动了子线程B,调用B.setDaemaon(True),...
