What does a b/b a do in Python?

where b is using the old value of a before a was reassigned to the value of b . Python first evaluates the right-hand expression and stores the results on the stack, then takes those two values and assigns them to a and b . That means that a + b is calculated before a is changed.

What does a b/b a/b mean in Python?

a, b = b, a + b. It’s a tuple assignment, means (a, b) = (b, a + b) , just like (a, b) = (b, a) Start from a quick example: a, b = 0, 1 #equivalent to (a, b) = (0, 1) #implement as a = 0 b = 1.

How do you get AB in Python?

Use the % operator to calculate a mod b
  1. a = 11.
  2. b = 3.
  3. a_mod_b = a % b.
  4. print(a_mod_b)

What does temp mean in Python?

Why is there AB in front of string Python?

What is data type b in Python?

Python b string consists of bytes data, which means the literal that represents integers are between 0 and 255. Python b string and Python string have one major difference, which is its data type. … By adding that prefix b in front of a python normal string, we modified its data type from string to bytes.
