Python Program to print strings based on the list of prefix
When it is required to print strings based on the list of prefix elements, a list comprehension, the ‘any’ operator and the ‘startswith’ method are used.
Example
Below is a demonstration of the same
my_list = ["streek", "greet", "meet", "leeks", "mean"]
print("The list is : ")
print(my_list)
prefix_list = ["st", "ge", "me", "re"]
print("The prefix list is : ")
print(prefix_list)
my_result = [element for element in my_list if any(element.startswith(ele) for ele in prefix_list)]
print("The result is :")
print(my_result)Output
The list is : ['streek', 'greet', 'meet', 'leeks', 'mean'] The prefix list is : ['st', 'ge', 'me', 're'] The result is : ['streek', 'meet', 'mean']
Explanation
- A list of strings is defined and is displayed on the console.
- A list of strings is defined as ‘prefix_list’ and is displayed on the console.
- A list comprehension is used to iterate over the elements and check if an element in the list starts with any of the strings provided in the prefix list.
- If yes, the element is stored in a list.
- This is assigned to a variable.
- This is displayed as output on the console.
