In Python everything is object and string are an object too. Python string can be created simply by enclosing characters in the double quote.
var = “Hello World!”
In this tutorial, we will learn –
Various String Operators
There are various string operators that can be used in different ways like concatenating different string.
Suppose if a=guru and b=99 then a+b= “guru99”. Similarly, if you are using a*2, it will “GuruGuru”. Likewise, you can use other operators in string.
Python 2 Example
Since Python is an object-oriented programming language, many functions can be applied to Python objects. A notable feature of Python is its indenting source statements to make the code easier to read.
- Accessing values through slicing – square brackets are used for slicing along with the index or indices to obtain a substring.
- In slicing, if range is declared [1:5], it can actually fetch the value from range [1:4]
- You can update Python String by re-assigning a variable to another string
- Method replace() returns a copy of the string in which the occurrence of old is replaced with new.
- Syntax for method replace: oldstring.replace(“value to change”,”value to be replaced”)
- String operators like , [ : ], in, Not in, etc. can be applied to concatenate the string, fetching or inserting specific characters into the string, or to check whether certain character exist in the string
- Other string operations include
- Changing upper and lower case
- Join function to glue any character into the string
- Reversing string
- Split string
