Declaring Variables: Integers, float and string in Python.

In this post we will how to declare different type of variables in python.

Python is completely object oriented programming language and hence there is no requirement to declare variables separately.
However in this post we will look how to use the variables in Python.

 

Using Numbers: Integers and float & Strings in Python

Lets have a look how to use integers, float and strings in python.

user@ngelinux$ cat fourth.py 
#!/usr/bin/python

### Declaring and printing a integer variable
intvar=5
print(intvar)

### Declaring and printing a float variable
floatvar=5.199
print(floatvar)

### Using Strings
stringvar="hello"
print(stringvar)

#### Another way to define variable type specifically
#### making intvar to float
intvar2=float(5)
print(intvar2)

Output
Now lets run above program and see the variables got printed.
It means there is no need to declare variables’ type in python.

It is automatically taken by the interpreter.

user@ngelinux$ ./fourth.py 
5
5.199
hello
5.0
user@ngelinux$
