list in Python is a data structure that is a changeable or mutable ordered sequence of elements. Each element or value present in a list is called an item. In a Python program, lists are defined by having values between square brackets
countries = ["USA", "CHINA", "TURKEY"]
From the example given above, we can see that
countries is a list variable, while
"TURKEY" are all elements of the list.
To loop through a list in Python simply means to repeat something over and over in the items of a list, until a particular condition is satisfied.
We can loop through a list in Python using a
For (expression): statement(s)
expression given in the code above is usually a condition, and this
statement will execute when the condition is true.
In the code given below, we want to print all the items in the list one by one:
countries = ["USA", "CHINA", "TURKEY"] for x in countries: print(x)
forloop to create an expression, which will make
xbecome each item present in the list.
