今天写几行代码解决工作问题,程序运行报报'builtin_function_or_method' object is not subscriptable 错误, 将代码简写如下 litterPigs =[]forboarinrange(0,6): pig=[1,2,3,5]print(pig)try: litterPigs.append[pig]exceptBaseException as e:print(e) 运行结果为: 差了半天原因,最后发现是括号写错了,l...
of the sequence in the calculation, andserves as a default when the sequence is empty. function:该函数有两个参数 sequence:序列可以是str,tuple,list initial:固定初始值 reduce依次从sequence中取一个元素,和上一次调用function的结果做参数再次调用function。 第一次调用function时,如果提供initial参数,会以seq...

Note: Many of Python’s built-in functions are classes with function-style names. Good examples are str, tuple, list, and dict, which are classes that define built-in data types. These classes are listed in the Python documentation as built-in functions and you’ll find them in this tuto...

Applying the LGB rule means that the function is always available, and that no import statement is needed to access it.[54] You’ve already encountered many of the built-in functions, such as len, open, type, list, map, range, reload. You can find them listed with the standard ...
