Python Program To Print Every Index of Duplicate Elements in List

[@pavankumarlucky5963]

for multiple duplicate elements: num=int(input()) l=[int(input()) for i in range(num)] orig=[] dup=[] for i in l: if i not in orig: orig.append(i) else: dup.append(i) print(l) print(orig) print(dup)

Dear sister your effort are very special. God bless you

You are teaching very good.Can you make video for this question: Write user defined function to show scope of global and local variables. In python.

can you please tell, How to perform same operation for nested in list...?

[@buvaneshkumar5626]

I see you're hard coding the repeated element in the code. But in most cases, we won't be knowing what was the repeated element.

[@vasundharajayswal5451]

def dup_elmnt(list1): indx_list=[] temp=[] for j in list1: if list1.count(j)>=2 and j not in temp: for i in range(len(list1)): if list1[i]==j: indx_list.append(i) temp.append(j) else: pass return indx_list

[@sasidharreddy5008]

Here you know the duplicate values and you added them in the if condition and got those indexes what if you dont the elements which got duplicated in such cases how to do.?

[@minalhombre6821]

Thank you.

Is it possible to print the multiple duplicate element's index at same time??

[@eswarkalakata5183]

#finding the index for diplicate eliments l = [1,2,3,3,1,0,1] count = 0 s = set() v = [] for indx,value in enumerate(l): if value not in s: s.add(value) else: v.append([value,indx]) print(v)

[@javierLopez-zb3oe]

Is there a super efficient way to do this? I tried with panda and it takes about the same time. I'm dealing with lists of 100k elements. Any advice? I'd really appreciate it! Thanks!

[@daveclosinger6697]

Find them by hand manually

[@ahsanmomin4110]

names=['alex','hannahe','james'] Find how many 'e' and 'a' are there in list output [2,3,2] How to solve this one please asist??

[@yukeshteach1181]

l1=["alex","hannahe","james"] #to find out no of and e l2=[] a="" count=0 for i in range(0,len(l1)): a=l1[i] count=0 for j in range(0,len(a)): if a[j]=='a'or a[j]=='e': count=count+1 l2.append(count) print(l2)

[@rajeshs2840]

This code will give index of non duplicate numbers also. Sloppy code

[@keshavmittal6365]

Mam how can we make similar program when we input the list values from user and we don't know the repeated values

[@AmulsAcademy]

n = int(input("How many elements you want in list:")) list1 = [] for i in range(n): list1.append(eval(input())) print("input list is:",list1) elem = eval(input("select the element: ")) list2 = [i for i in range(len(list1)) if list1[i]==elem] print("index of",elem,"is:",list2) :)

@@AmulsAcademy thank you

[@CrazyFunCricket]

you have hardcoded the 1 its bad

[@harpreetsidhu606]

i know that we can know the first occurence of the element by index method in lists,but can we do this same with because sets are unordered and unchangeable sometimes it prints only duplicate elements or without duplicate elements.like union( ) and update method exclude duplicate elements.

Can u make a program in python to check is user name valid or not

I will try :)

helloo.. can we add else statement to the above code??

Yes :)

[@keishalorejo7217]

how do you do this in java?

Work for google, or big companies that require such skills, most pay a huge salary, especially in the medical field.

[@omsrisaikrishna9618]

Please tell me, how it will be compiler run step by step

[@AmulsAcademy]

That program will print all the index of given duplicate element in list. 1 take a list with duplicate values. 2. we are using list comprehension method, i for i in range(len(list1)) ---------------------> it will print all the index of list element. but we want index of particular duplicate element, for example 1. so i will take if list1[i] == 1 condition. so it will give all the index duplicate element 1. 3 .next we will print that. :)

please do this for gerenal code

It will work for any list. If you want to take user entered list then, instead of taking list directly take like this. num = int(input("enter the list length:")) list1 = [int(input()) for i in range(num)] :)

List1 = [ken, di, py] #firstname List2 = [py, thon, prog] #lastname List2 = [3,3,1] #grades How to get the max or min grades with getting the parralel index of list 1 and list2 My prob is only 0 index is readable But i need output is Ken py 3 Di thon 3

[@technicalanalytics1391]

Second Maximum Number in a List Description Given a list of numbers, find the second largest number in the list. Note: There might be repeated numbers in the list. If there is only one number present in the list, return 'not present'. Examples: Input 1: [7, 2, 0, 9, -1, 8] Output 1: 8 Input 2: [3, 1, 4, 4, 5, 5, 5, 0, 2, 2] Output 2: 4 Input 2: [6, 6, 6, 6, 6] Output 2: not present can you explain this problem
