Python Variables

 

  • Python doesn’t have a specific “keyword” for variables.
  • No need to specify the type of data for given variable.
  • You can change the value of that variable in the same programming file even further.

 

 

Data Types:

Variable Type Declaration
Integer x=5
Float f=0.1
String s=”zeroones”
Boolean b=True

 

Example:

simple value assign to various data type.

x = 5 #interger
y = 0.5 #float
b = True #Boolean
s = "John" #string

 

 

Variables name are case sestivite and you can write string in single quotes and double quotes as well.

 

But in the python data type casting concept available. If you want to convert one data type to another data type then go for type conversion.

x = 25
y = '3'
z = "54"

print(type(x))   # output int
print(type(y))   # output string
print(type(z))  # output string

x1 = str(x)    # x interger to string
y1 = int(y)    # y char to interger
z1 = float(z)  # z string to float

print(x1) 
print(y1)
print(z1)

print(type(x1))  # output string
print(type(y1))  # output integer
print(type(z1))  # output float

Function “type()”: This Function return the type of variable, as you saw in the previous example.
