Python has two basic function for sorting lists:sortandsorted. Thesortsorts the list in place, while thesortedreturns a new sorted list from the items in iterable. Both functions have the same options:keyandrev
In this example, we will declare and assign the list, will print their types, and will print the list. To find the type of an object – we usetype() method. # declaring listslist1=[10,20,30,40,50,10,60,10]list2=["Hello","IncludeHelp"]list3=["Hello",10,20,"IncludeHelp"]# ...

Print list in Python using list comprehension List comprehension in Python offers a concise and elegant way to print a list by iterating over its elements and performing an operation on each element within a single line of code. This method is often preferred for its simplicity and readability....
The Python Imaging Library (PIL) and its modern fork Pillow serve as foundational tools for basic image manipulation, supporting operations across common formats like JPEG, PNG, BMP, and TIFF. OpenCV extends these capabilities with advanced computer vision features, while scikit-image provides scientif...
Method 1: One method to solve the problem is by first creating a map of sum of elements of each tuple in Python. Then sum up all elements of the map which will be our final result. # Python program to perform summation of tuple# in list using sum and map# Initializing and printing ...
# Printing final result and its type print(res) Output: 9. Using splitlines() method You can use the splitlines() method in Python for this conversion. We can split a string into a list based on new line characters (\n). This method is used to separate text into lines. ...
