String Slicing In python
Hello guys,good Evening all of you,
So,we will learn about String Slicing in today's session.So are you exicated?
Let's start today's session.
String Slicing:
String slicing is a technique used to extract a specific portion of a string in Python by specifying the start and end indices of the substring you want to extract.

To slice a string, you can use the syntax string[start:end]. This will extract the portion of the string that starts at the index specified by "start" and ends at the index specified by "end-1". For example, the string "Hello, world" could be sliced to extract the substring "world" using the code "string[7:12]".

If you don't specify a "start" index, Python assumes that you want to start at the beginning of the string. For example, the code "string[:5]" would extract the first 5 characters of the string.

Similarly, if you don't specify an "end" index, Python assumes that you want to slice to the end of the string. For example, the code "string[7:]" would extract all the characters of the string starting at index 7.

You can also use negative indices to slice a string from the end. For example, the code "string[-5:]" would extract the last 5 characters of the string.

Finally, you can use a step parameter to extract every nth character of a string. The syntax for this is string[start:end:step]. For example, the code "string[::2]" would extract every other character of the string.

String slicing is a powerful technique that allows you to manipulate and extract data from strings in Python. With some practice, you'll be able to use it to extract any substring you need!
**Tags:**
Strings: String slicing is used to manipulate and extract substrings from strings.
Slicing: String slicing involves extracting a portion of a string by specifying the start and end indices of the substring.

Indices: String slicing uses index numbers to specify the start and end points of the substring to be extracted.

Substrings: String slicing is used to extract a substring from a larger string.

Syntax: String slicing involves using the correct syntax to specify the start and end indices of the substring to be extracted.

Start index: The start index is the index position in the string where the substring extraction begins.

End index: The end index is the index position in the string where the substring extraction ends.

Step parameter: The step parameter is an optional parameter used in string slicing to specify the step size for extracting every nth character of the substring.

Negative indices: String slicing can also use negative indices to specify positions relative to the end of the string.
