When constructing a slice, as in[6:11], the first index number is where the slice starts (inclusive), and the second index number is where the slice ends (exclusive), which is why in our example above the range has to be the index number that would occur after the string ends. When...

We’re not changing the underlying string that was assigned to it before. We’re assigning a whole new string with different content. In this case, it was pretty easy to find the index to change as there are few characters in the string.How are we supposed to know which character to ch...
string.index(sub[, start[, end]])方法的基本定义如下：- string：需要检索的字符串。- sub：要查找的子字符串。-start：可选参数，指定开始查找的索引位置，默认为0，即从字符串的第一个字符开始查找。- end：可选参数，指定结束查找的索引位置（不包含该位置）。二、方法的返回值 string.index方法的返回值...
#print(s4[10]) #IndexError: string index out of range #获取字符串的长度:len() #遍历字符串,和list,tuple的用法完全相同,通常与for循环搭配使用 for element in s4: print(element) for index in range(0,len(s4)): print(s4[index])

The index of the first character of a string is 0. There is no separate character type. A character is simply a string of size 1. Here's how to get the character at a specific index.Python Copy word = 'Python' word[0] # Character in position 0.The output is:...
