Write a Python program to print the index of a character in a string.Sample Solution:Python Code:# Define a string 'str1'. str1 = "w3resource" # Iterate through the characters of the string using enumeration. # 'index' contains the position of the character, and 'char' contains the ch...
在Python中,我们可以使用以下代码实现: returnindex 1. 这段代码中,我们使用return语句将当前索引值返回。 完整代码示例 下面是将以上四个步骤整合在一起的完整代码示例: defindex_of_substring(string,substring):string_list=list(string)forindex,charinenumerate(string_list):ifchar==substring[0]:# 判断当前字符...

Return the lowest index in the string where substring sub is found using the numpy.char.index() method in Python Numpy. The method returns the output array of ints. Raises ValueError if sub is not found. The first parameter is the input array. The second parameter is the substring...
#include<iostream> using namespace std; int getLastIndex(string& str, char ch) { for (int i = str.length() - 1; i >= 0; i--) if (str[i] == ch) return i; return -1; } int main() { string str = "hello"; char ch = 'l'; int index = getLastIndex(str, ch); if...
