How to compare more than 2 Lists in Python?
Question: I am new to Python as well new on Stackoverflow , can anyone tell me
efficient(pythonic) way to compare more than 2 Lists ? I want to enlist all
the elements of all 3 Lists and display in such fashion that user will be able
to know that which element is present in all 3 List OR element present in List
1 but not in List 2 OR which elements are duplicates. I have done comparison
using nested loops.

    
    
    List1 = [10,10,11,12,15,16,18,19]  
    List2 = [10,11,13,15,16,19,20]  
    List3 = [10,11,11,12,15,19,21,23] 
    
    # Checking whether List 1 value present in List2 and List 3
    for l1 in List1:  
        if l1 in List2: 
            List2.remove(l1)  
            if l1 in List3: 
                List3.remove(l1)  
                print(l1," ",l1," ",l1)  
            else:  
                print(l1," ",l1," ","NA")  
        else:
            if l1 in List3:   
                List3.remove(l1)
                print(l1," ","NA"," ",l1)
            else:
                print(l1," ","NA"," ","NA")
    
    # Checking whether List 2 value present in List3
    for l2 in List2:
        if l2 in List3:
            List3.remove(l2)
            print("NA"," ",l2," ",l2)
        else:
            print("NA"," ",l2," ","NA")
    
    # Checking for values present only in List 3
    
    for l3 in List3:
        print("NA","NA",l3)
    
    --- Output---
    List1 List2 List3
    10   10   10
    10   NA   NA
    11   11   11
    12   NA   12
    15   15   15
    16   16   NA
    18   NA   NA
    19   19   19
    NA   13   NA
    NA   20   NA
    NA NA 11
    NA NA 21
    NA NA 23
    NA   20   NA
    NA NA 11
    NA NA 21
    NA NA 23
    

Is there any better way to compare the Lists ?


Answer: 
    import pandas as pd
    d = {'List1' : pd.Series(List1),'List2' : pd.Series(List2),'List3': pd.Series(List3)}
    
    df = pd.DataFrame(d)
    
    print(df)
    
    ***OUTPUT:***
          List1  List2  List3
          10      NaN     NaN
          11      11     11
          12      NaN     12
          15      15     15
          16      16     NaN
          18      NaN    NaN
          19      19     19
          NaN     13     NaN
    

Using Pandas you can compare the multiple list, while the empty coloumn would
be automatically filled as NaN.

Pandas is a Data visualization library of python

Install pandas by : pip install pandas
