#python #strings #tutorial #beginners

strings

A string can be declared using either single' or double" quotations.

### A string with double quotation
my_string1 = "Hello, Rishi"
### A string with single quotation
my_string2 = 'Hello, Rishi'
print(my_string1)
print(my_string2)
Enter fullscreen mode Exit fullscreen mode

Using single' and double" quotations

Both single' and double" quotations can be used while declaring a string.

### A string with mixed quotations
string_mixed = "Hello, Rishi: 'You are amazing'!"
print(string_mixed)

string_mixed2 = 'Hello, Rishi: "You are amazing"!'
print(string_mixed2)
Enter fullscreen mode Exit fullscreen mode

Escaping single' and double" quotations

To use the same quotations within the string declaration, an escape character \ needs to be used.

 ### A string with mixed quotations using an escape character
string_mixed3 = "Hello, Rishi: \"You are amazing\"!"
print(string_mixed3)

string_mixed4 = 'Hello, Rishi: \'You are amazing\'!'
print(string_mixed4)
Enter fullscreen mode Exit fullscreen mode

multiple_lines = """Hello,

My name is Rishi.

Welcome.
"""
print(multiple_lines)

"""Hello,

very 

long comments.
"""

Adding a string to another string 

### Adding a string to another string

greet = "Hello"
name = "Rishi"

print(greet + name);
print(greet + ' ' + name);
Enter fullscreen mode Exit fullscreen mode

Adding a string to a number!!! Wait? 😕

Before adding a string to a number, we need to convert it first using str().

### Adding a string to a number!!! Wait?
greet = "Hello"
number_as_string = str(2020)
float_as_string = str(0.12345)

print(greet + number_as_string);
print(greet + ' ' + number_as_string);
print(greet + ' ' + float_as_string)
Enter fullscreen mode Exit fullscreen mode
