Python3 set method function example, python3set

Add (add element)

Name = set (['Tom ', 'Lucy', 'ben']) name. add ('juny') print (name) # output: {'Lucy ', 'juny', 'ben', 'Tom '}

Clear (clear all elements)

Name = set (['Tom ', 'Lucy', 'ben']) name. clear () print (name) # output: set ()

Copy (copy set)

Name = set (['Tom ', 'Lucy', 'ben']) new_name = name. copy () print (new_name) # output: {'Tom ', 'Lucy', 'ben '}

Difference (returns two or more sets of different elements and generates a new set)

A = set ([2, 3, 4, 5]) B = set ([3, 4]) C = set ([2]) n = n1.difference (n2, n3) print (n) # output: {5}
# Return the elements that are not in Set B and set C in set A and generate A new set.

Difference_update (delete the elements in set A that exist in Set B .)

A = set ([2, 3, 4, 5]) B = set ([4, 5]) A. difference_update (B) print (A) # output: {2, 3}

Discard (remove element)

N = set ([2, 3, 4]) n. discard (3) print (n) # output: {2, 4}

Intersection (take the intersection and generate a new set)

N1 = set ([2, 3, 4, 5]) n2 = set ([4, 5, 6, 7]) n = n1.intersection (n2) print (n) # output: {4, 5}

Intersection_update (take the intersection and modify the original set)

N1 = set ([2, 3, 4, 5]) n2 = set ([4, 5, 6, 7]) n1.intersection _ update (n2) print (n1) # output: {4, 5}

Isdisjoint (determines the intersection. False is returned; True is returned)

N1 = set ([2, 3, 4, 5]) n2 = set ([4, 5, 6, 7]) print (n1.isdisjoint (n2) # output: False

Issubset)

A = set ([2, 3]) B = set ([2, 3, 4, 5]) print (A. issubset (B) # output: True # A is A subset of B

Issuperset (determine parent set)

A = set ([2, 3]) B = set ([2, 3, 4, 5]) print (B. issuperset (A) # output: True # B is the parent set of

Pop (remove an element randomly)

N = set ([2, 3, 4, 5]) n1 = n. pop () print (n, n1) # output: {3, 4, 5} 2

Remove (remove a specified element)

N = set ([2, 3, 4, 5]) n. remove (2) print (n) # output: {3, 4, 5}

Symmetric_difference (intersection and generate a new set)

A = set ([2, 3, 4, 5]) B = set ([4, 5, 6, 7]) print (. symmetric_difference (B) # output: {2, 3, 6, 7}

Symmetric_difference_update (take the intersection and change the original set)

A = set ([2, 3, 4, 5]) B = set ([4, 5, 6, 7]). symmetric_difference_update (B) print (A) # output: {2, 3, 6, 7}

Union (obtains the union set and generates a new set)

A = set ([2, 3, 4, 5]) B = set ([4, 5, 6, 7]) print (. union (B) # output: {2, 3, 4, 5, 6, 7}

Update (take the Union set and change the original set)

A = set ([2, 3, 4, 5]) B = set ([4, 5, 6, 7]). update (B) print (A) # output: {2, 3, 4, 5, 6, 7}
