2 在Python项目中,新建并打开一个空白的python文件(比如:test.py)。3 在python文件编辑区中,输入:“from array import *”,导入 array 模块内容。4 插入语句:“arr = array('u', 'EDCBA')”,点击Enter键。5 插入语句:“arr.reverse()”,点击Enter键。6 再输入:“print(ar...
Here, we are using reversed() function to reverse an array. This function returns reversed iterator object ,so we convert it into array by using array.array() function. Below is the Python code given: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 # import array module import array # integ...

To reverse an array in Python using NumPy, various methods such as np.flip(), array slicing, and np.ndarray.flatten() can be employed. np.flip() reverses elements along a specified axis, array slicing offers a simple syntax for reversing, while flipud() and fliplr() flip arrays vertically...
使用reverse()内置的reverse迭代来反转字符串。从而得到一个反向迭代器,然后循环遍历字符串中的元素。例如: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>>foreleminreversed('TURBO'):...print(elem)OBRUT 使用reversed()不会修改原始字符串(由于Python中的字符串是不可变的,因此不会起作用。) ...
str、byte、bytearray 只包含可打包对象的集合,包括 tuple、list、set 和 dict 定义在模块顶层的函数(使用def定义,[lambda]()函数则不可以) 定义在模块顶层的内置函数 定义在模块顶层的类 某些类实例,这些类的dict属性值或 [__getstate__()]()函数的返回值可以被打包(详情参阅打包类实例这一段) ...
