2. list2 = [1, 1, 1]
3. difference = [] initialization of result list.
4. zip_object = zip(list1, list2)
5. for list1_i, list2_i in zip_object:

How do you subtract elements from a list in Python?

Perform List Subtraction in Python

1. list1 = [“Ram”,”Arun”,”Kiran”] list2 = [16,78,32,67] list3 = [‘apple’,’mango’,16,’cherry’,3.4]
2. #input list1 = [4,8,1,9,5] list2 = [1,4,2,6,7] #output list3 = [3,4,-1,3,-2] New List = Elements of List1 – Elements of List2.

How do you find the difference between two lists in Python?

Pythonic Ways to Find the Difference Between Two Lists

1. Use set() to find the difference of two lists. In this approach, we’ll first derive two SETs (say set1 and set2) from the LISTs (say list1 and list2) by passing them to set() function.
2. Without set(), using nested loops.
3. Without set(), using list comprehension.

Can you subtract tuples?

When it is required to subtract the tuples, the ‘map’ method and lambda function can be used. The map function applies a given function/operation to every item in an iterable (such as list, tuple). It returns a list as the result.

How do you subtract in Python?

To subtract the numbers, I have used sub=a-b. The function is returned as return sub. To get the output, I have used print(“Result is: “,subtraction(number1,number2)).

Can you subtract two arrays in Python?

subtract() in Python. numpy. subtract() function is used when we want to compute the difference of two array.It returns the difference of arr1 and arr2, element-wise.

How do you subtract two arrays?

Find the minimum non-zero element in the array, print it and then subtract this number from all the non-zero elements of the array. If all the elements of the array are < 0, just print 0.

What is set () in Python?

Python | set() method set() method is used to convert any of the iterable to sequence of iterable elements with distinct elements, commonly called Set. Syntax : set(iterable) Parameters : Any iterable sequence like list, tuple or dictionary. Returns : An empty set if no element is passed.

How do you compare two sets in Python?

The set() function and == operator

1. list1 = [11, 12, 13, 14, 15]
2. list2 = [12, 13, 11, 15, 14]
3. a = set(list1)
4. b = set(list2)
5. if a == b:
6. print(“The list1 and list2 are equal”)
7. else:
8. print(“The list1 and list2 are not equal”)

How do you find the difference between two tuples in Python?

Tuples are compared position by position: the first item of the first tuple is compared to the first item of the second tuple; if they are not equal, this is the result of the comparison, else the second item is considered, then the third and so on.

How do you convert a tuple to a list?
