Output:lool Python slice works with negative indexes too, in that case, the start_pos is excluded and end_pos is included in the substring. s1 = s[-4:-2] print(s1) Output:or Python string slicing handles out of
In addition, we canaccess just a specific characteror aslice of charactersof a string. We might want to do this, for example, if we have a text that’s too long to display and we want to show just a portion of it. Or if we want to make an acronym by taking the first letter of...
You can return a range of characters by using the slice syntax. Specify the start index and the end index, separated by a colon, to return a part of the string. ExampleGet your own Python Server Get the characters from position 2 to position 5 (not included): ...
You can also use negative index numbers to slice a string. As we went through before, negative index numbers of a string start at -1, and count down from there until we reach the beginning of the string. When using negative index numbers, we’ll start with the lower number first as it...

Here’s how: # Using slicing to reverse a string my_string = 'Hello, World!' reversed_string = my_string[::-1] print(reversed_string) The [::-1] syntax in the above code tells Python to slice the entire string and step backward by -1, which effectively reverses the string....
在python中,list, tuple以及字符串等可以遍历访问的类型都可以应用slice访问。slice本身的意思是指切片,在这些可以遍历访问的类型中截取其中的某些部分。比如如下的代码: >>> l = range(10) >>> l [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] >>> l[1:5] ...
In that case, I specify the starting point of the slice and the end point of the slice. 所以在这种情况下,我得到字母“Pyt” So in this case, I get the letters "Pyt." 因此Python向我返回一个新字符串。 So Python returns a new string to me. 我也可以使用负索引进行切片。 I can also ...
