coding snipets in python

1) Assigning elements to different list

# Python3 code to demonstrate  
# to assign variables from list element 
# using list comprehension  
  
# initializing list   
test_list = [1, 4, 5, 6, 7, 3] 
  
# printing original list 
print ("The original list is : " + str(test_list)) 
  
# using list comprehension 
# to assign variables from list element 
var1, var2, var3 = [test_list[i] for i in (1, 3, 5)] 
  
# printing result 
print ("The variables are : " +  str(var1) + 
                           " " + str(var2) +
                            " " + str(var3)) 


2)Accessing elements from a tuple

# Python3 code to demonstrate  
# get nth tuple element from list 
# using list comprehension  
  
# initializing list of tuples 
test_list = [(1, 'Rash', 21), (2, 'Varsha', 20), (3, 'Kil', 19)] 
  
# printing original list  
print ("The original list is : " + str(test_list)) 
  
# using list comprehension to get names 
res = [lis[1] for lis in test_list] 
      
# printing result 
print ("List with only nth tuple element (i.e names) : " + str(res))

3)Deleting different dictionary elements

# Creating a dictionary 
myDict = {1: 'python', 2: 'is', 3: 'fun'} 
  
# Iterating through the keys 
for key in myDict.keys(): 
    if key == 2:  
        del myDict[key] 
  
# Modified Dictionary         
print(myDict)
