在Python中一个脚本(Script)是一个将要被当做主模块(main)执行的python文件。模块(Module)是一个以.py结尾的python文件,在文件中我们定义了函数、类,准备以后重用这些代码块。Python中模块的名字,就是以.py为后缀的文件的文件名,例如fibo.py,那么模块名就是fibo。__name__变量保存了引用的模块的名字,当模块被当...
“nopython mode”是Numba库中的一个执行模式,旨在通过JIT(Just-In-Time)编译技术将Python代码转换为高效的机器码,从而提高性能。在“nopython mode”下,Numba会尝试将尽可能多的Python代码编译为机器码,而绕过Python解释器的运行时开销。这通常意味着更快的执行速度和更低的内存占用,尤其是在处理大量数据或执行计算...
在Python 3.2版本号之后,同意输入Windows或Mac的换行符。当採用exec模式时,不须要在每一个行后面输入换行符;在这个版本号之后添加了优化參数。 样例: #compile() str = "for i in range(0,10): print(i)" c = compile(str,'','exec') # 编译为字节代码对象 exec(c) # 运行 str2 = "3*x + 4*...
