Variable Name and their types in python
Variable Name and their types in python
By default a variable’s data type is string unless we assign a value to it during declaration.
If we declare a variable and take value from user then it will be treated as string variable.
So we have to change its data type and then take value from user.
In [1]:
# types of variables
x = 5
y = 1.5
z = "hello"
print (x)
print(type(x))
print (y)
