print("Reversed array is:", rev_arr) Output: 1 2 3 4 Original array is: [10, 20, 30, 40, 50, 60] Reversed array is: [60, 50, 40, 30, 20, 10] Using array modile Now, we will see different ways to reverse an array using array module in Python. Using a reverse() method...
To iteraterange(len(arr)-1, -1, -1)use for loop, it will return an array of elements in the reversing order. Related:In Python, you can use for loop to iterate iterable objects in reversing order and get them inbackwards directions. # Reverse an array using for loop # Initialize the...
As we did earlier with lists, we can reverse an array in Python built with Numpy usingslicing. We create a newNumPyarray object which holds items in a reversed order. import numpy as np #The original NumPy array new_arr=np.array([1,3,5,7,9]) print("Original Array is :",new_arr)...
The following example shows how to reverse an array in Python using for loop. importarrayasarr a=arr.array('i',[10,5,15,4,6,20,9])b=arr.array('i')foriinrange(len(a)-1,-1,-1):b.append(a[i])print(a)print(b) It will produce the followingoutput− ...
这道题主要是要明白Base64的加密原理,为了让各位师傅们明白的清楚一点我用python实现一下Base64加解密原理: #加密defb64encode(str):b64='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'b=''Mi=''foriinstr:b+=format(ord(i),'08b')#在python中把一个数转换成二进制的形式的时候输出来的不...
照本宣科写出解密脚本,在 python 中注意没有自然溢出,需要 +256 取模: v4 =0;v5 =0foriinrange(len_buf): v5 = (v5 +1) %128v4 = (v4 + S[v5]) %128S[v5],S[v4] = S[v4],S[v5] buf[i] = (buf[i] - S[ (S[v4]+S[v5])%128])%256 ...

Python中 reverse()是列表的内置方法,无参数,无返回值,reverse()会改变列表(原地反转),因此无需返回值。字典、元组、字符串不具有reverse()方法,如果调用将会返回一个异常. >>> help(list.reverse) Help on method_descriptor: reverse(...) L.reverse() -- reverse *IN PLACE* >>> l=[1,2,3,4,5]...
