How do I check if a list is a subset of another list in Python using list comprehension?

To check if a list is a subset of another list in Python using list comprehension, you can follow these steps:
1. Define a function to check if the first list is a subset of the second list:
1
2
3
4
def is_subset(list1, list2):
return all(item in list2 for item in list1)
2. Call theis_subset function and pass the two lists to be checked:
1
2
3
4
5
6
7
8
9
list1 = [1, 2, 3]
list2 = [1, 2, 3, 4, 5]
if is_subset(list1, list2):
print("list1 is a subset of list2")
else:
print("list1 is not a subset of list2")
In theis_subset function, a list comprehension is used to iterate over each item inlist1 and check if it exists inlist2. Theall function is then used to verify that all items inlist1 are present inlist2.
If all items inlist1 are found inlist2, the function returnsTrue, indicating thatlist1 is a subset oflist2. If any item inlist1 is not present inlist2, the function returnsFalse, indicating thatlist1 is not a subset oflist2.
The use of list comprehension and theall function allows for concise and efficient checking of whether one list is a subset of another in Python.
You can modify the code to check the subset relationship between any two lists by passing different lists to theis_subset function.
