Slicing
Slicing in Python is a feature that enables accessing parts of the sequence. In slicing a string, we create a substring, which is essentially a string that exists within another string. We use slicing when we require a part of the string and not the complete string. Syntax :
string[start : end : step]
- start : We provide the starting index.
- end : We provide the end index(this is not included in substring).
- step : It is an optional argument that determines the increment between each index for slicing.
Example 1 :
python3
# declaring the string str ="Geeks for Geeks !"# slicing using indexing sequence print(str[: 3]) print(str[1 : 5 : 2]) print(str[-1 : -12 : -2]) |
Output
Gee ek !seGrf
Example 2 :
python3
# declaring the string str ="Geeks for Geeks !"print("Original String :-") print(str) # reversing the string using slicing print("Reverse String :-") print(str[: : -1]) |
Output
Original String :- Geeks for Geeks ! Reverse String :- ! skeeG rof skeeG
How To Index and Slice Strings in Python?
The Python string data type is a sequence made up of one or more individual characters that could consist of letters, numbers, whitespace characters, or symbols. As the string is a sequence, it can be accessed in the same ways that other sequence-based data types are, through indexing and slicing.
