Hey guys, in this blog we will see a Python Program to Concatenate Two Lists. Example 1: Using + operator Output [1, ‘a’, 3, 4, 5] + operator can be used to simply join 2 lists. Example 2: Using iterable unpacking operator * Output [1, ‘a’, 2, 3] * is used to unpack all the […]

Hey guys, in this blog we will see a Python Program to Split a List Into Evenly Sized Chunks. Example 1: Using yield Output [[1, 2], [3, 4], [5, 6], [7, 8], [9]] Using yield to print the results. Chunk size is 2 so it will start like printing list_a[0:2] then list_a[2:4] then list_a[4:6] and

Hey guys, in this blog we will see a Python Program to Check if a Key is Already Present in a dictionary. Using in keyword Output present Here we are simply checking if key 2 is present in our dictionary or not. Note we can check for keys using the following also: Check out our

Hey guys, in this blog we will see a Python Program to Copy a File. Using shutil module Method Preserves Permissions Supports Directory as Destination Copies Metadata Supports file object copy() Yes Yes No No copyfile() No No No No copy2() Yes Yes Yes No copyfileobj() No No No Yes Here we have used the

Hey guys, in this blog we will see a Python Program to Catch Multiple Exceptions in One Line. Multiple exceptions as a parenthesized tuple Input 1 a 2 Output 1 can only concatenate str (not “int”) to str Input 2 a b Output 2 invalid literal for int() with base 10: ‘b’ We have used

Hey guys, in this blog we will see a Python Program to Slice Lists. The format for list slicing is [start:stop:step]. start is the index of the list where slicing starts. stop is the index of the list where the slicing ends. step allows you to select the nth item within the range start to stop. Get all the Items Output [1, 2, 3,

Hey guys, in this blog we will see a Python Program to Iterate Over Dictionaries Using for Loop. Example 1: Access both key and value using items() Output a messi b ronaldo c neymar Here we have used dt.items() which will print [(‘a’,’messi’),(‘b’,’ronaldo’),(‘c’,’neymar’)]. And then we are simply every element of the list in a

Hey guys, in this blog we will see a Python Program to Check If a List is Empty. Example 1: Using the Boolean operation Output The list is empty This is the easiest method to check an empty list. If my_list is empty it will work as a False. We have used if not my_list

Hey guys, in this blog we will see a Python Program to Sort a Dictionary by Value. Example 1: Sort the dictionary based on values Output {3: 3, 2: 4, 1: 6, 8: 9} In this method, we are sorting our dictionary on the basis of values (not keys). We have used the sorted() function

Hey guys, in this blog we will see a Python Program to Flatten a Nested List. Example 1: Using List Comprehension Output [2, 1, 1, 2, 3, 1, 2, 3, 4, 5, 6, 7] Example 2: Using Nested for Loops (non pythonic way) Output [2, 1, 1, 2, 3, 1, 2, 3, 4, 5, 6,
