If we use a larger number for our stride parameter, we will have a significantly smaller substring: print(ss[0:12:4]) Copy Output Sya Specifying the stride of 4 as the last parameter in the Python syntaxss[0:12:4]prints only every fourth character. Again, let’s look at the character...
What is String Slicing in Python String slicing is an approach that allows you to extract the substring of the given string, not the substring itself, even if you can extract specific characters.In Python, two ways exist to extract a substring from the given string. ...
