Variable in Python

Variable names in python can be a group of english alphabet, digits or underscore
No space or special symbol is allowed except underscore.
Variable names are case sensitive in python
First Character of the variable name can not be digit.

variables in python are declared as following.

a=10
b=”sharp tutorial”
c=5.4

Python dont need to declare the type of the variables as it automatically converts the variable based on the value.
As you see in the above example the int , float or string value is stored in the same type of the variable.

print command is used to print on the screen.

a=10
msg="welcome to sharp tutorial"
print(a)
print(msg)

Output:
10
welcome to sharp tutorial

Python add two int or float numbers(int & int , int & float , float & int)
like

a=3
b=4
print(a+b)

Output:
7

a=4.5
b=7
print(a+b)

Output:
11.5

Python concatenate two variables if both are string as following

a="sharp"
b="tutorial"
print(a+b)

Output:
sharp tutorial

If we try to add number with string it gives the error

a=10
b="hello"
print(a+b)

Output:
TypeError: cannot concatenate ‘str’ and ‘int’ objects

Following is the output for all above programs
