Here in this tutorial, we would learn how to use strings in Python? We would code here to add different strings together. Initially, we should know what a string is so, a String in python is surrounded by single quotes or a double quotes i.e. ' ' or " ".
Problem statement
Given a string and we have to add a greeting message like Hello with the string and return it using python program.
We are given with string of some peoples name and all we got to do is to add "Hello" before their names in order to greet them. If the string already begins with "Hello", then return the string unchanged.
Example
greeting('Santosh') = 'Hello Santosh'
greeting('Ram') = 'Hello Ram'
greeting('Hello Shyam') = 'Hello Shyam'
Solution
Now this problem is a bit complex as we have to check whether "Hello" is attached initially or not!
We can solve this problem by just adding an if statement.
Code
def greeting(str):
if len(str) >= 5 and str[:5] == 'Hello':
return str
return 'Hello ' + str
print (greeting('Prem'))
print (greeting('David'))
print (greeting('Hello Watson!'))
Output
Hello Prem
Hello David
Hello Watson!
In the last line of our code while typing string Hello we have provided space so that Hello and the name do not join together and look ugly.
To understand the above program, you should have the basic knowledge of the following Python topics:
