Variables - containers for storing data values.
- can be declared either by using single or double quotes.
- care-sensitive
Creating Variables
Example
x = 5
y = "John"
print(x)
print(y)
Variables do not need to be declared with any particular type, and can even change type after they have been set.
x = 4 # x is of type int
x = "Sally" # x is now of type str
print(x)
Casting
If you want to specify the data type of a variable, this can be done with casting.
x = str(3) # x will be '3'
y = int(3) # y will be 3
z = float(3) # z will be 3.0
Get the Type
You can get the data type of a variable with the type() function.
x = 5
y = "John"
print(type(x))
print(type(y))
