In Python, strings are among the most widely used types. They are easily made by simply surrounding characters in quotations. Python treats single quotes and double quotes the same way. Assigning a value to a variable and creating a string is really straightforward.
Example:
var1 = ‘Hello World!’
var2 = “Python Programming”
Python doesn’t have a character type; as they are viewed as one-length strings, they are also regarded as substrings.
Use the index or indices to get your substring along with the square brackets for slicing to access substrings.
#!/usr/bin/python
var1 = ‘Hello World!’
var2 = “Python Programming”
print “var1[0]: “, var1[0]
print “var2[1:5]: “, var2[1:5]
The outcome of running the aforementioned code is the following:
var1[0]: H
var2[1:5]: ytho
By (re)assigning a variable to another string, you can “update” an already-existing string. The new value may be connected to the old value or to an entirely separate string. For instance,
#!/usr/bin/python
var1 = ‘Hello World!’
print “Updated String :- “, var1[:6] + ‘Python’
The outcome of running the aforementioned code is the following:
updated String :- Hello Python
