Python Variables

March 2, 2020

A variable declaration is quit different than other programming languages.

Python has no command for declaring variable. When you assign any value then it will declared as variable.

a = 1
b = "One"

print(a)
print(b)

Also, same as other languages, we don’t need to declare variable type in Python. It will changes based on the assigned value.

There are some rules to declare variables in Python:

  • Must start with an alphabet or underscore
  • Can not start with a number
  • Contains only Alpha-Numeric Characters and underscores (A-Z, a-z, 0-9, _)
  • Case-Sensitive

For variable assignment, you can assign values to more than one variables in single line.

a, b, c = 1, 2, 3

print(a)

1


print(b)

2


print(c)
