lesson 2: Swapping of two values using Third variable and Without using third variable in python
wapping two values in Python is a common task that is often used in programming to exchange the contents of two variables. The concept is simple: if you have two variables, say a and b, swapping their values means that after the operation, a will hold the value of b and b will hold the value of a.
Traditional Approach
In many programming languages, swapping is done using a temporary variable. The process involves the following steps:
Assign the value of a to a temporary variable, temp.
Assign the value of b to a.
Assign the value of temp to b.
Pythonic Way
Python provides a more elegant way to swap values without using a temporary variable. This is done by using tuple packing and unpacking in a single line:
a = 5
b = 10
a, b = b, a
