# Sets Cheatsheet

1. **.add(item):** Adds a single item in a set\
   \
   `s1={12,34,23,56,78,45}`\
   `s1.add(3.14)                         # {12,34,23,56,78,45,3.14}`<br>
2. **.upate(iterables):** Updates a set by adding an iterable(list,set,tuple) in a set.\
   \
   `s1={12,34,23,56,78,45}`\
   `s1.update([1.23,4.20,5.67])         # {12,1.23,23,34,4.20,45,56,78,5.67}`<br>
3. **.union(set):** Returns a snew set consist of items from both sets.\
   \
   `s1={12,34,23,56,78,45}`\
   `s2={1.23,4.20,5.67}`\
   `s1.union(s2)                          # {12,1.23,23,34,4.20,45,56,78,5.67}`<br>
4. **.remove(item):** Removes a specific item from the set.\
   \
   `s1={12,34,23,56,78,45}`\
   `s1.remove(56)                   #  {12,34,23,78,45}`<br>
5. **.discard(item):** Removes a specific item from the set.\
   \
   `s1={12,34,23,56,78,45}`\
   `s1.discard(34)                  # {12,23,56,78,45}`<br>
6. **.pop():** Removes an item randomly from the set.\
   \
   `s1={12,34,23,56,78,45}`\
   `s1.pop()                           # {12,34,23,56,45}`<br>
7. **.clear():** Removes all the items from the set.\
   \
   `s1={12,34,23,56,78,45}`\
   `s1.clear()                       # set()`<br>
8. **.copy(set):** Copies items of one set into another\
   \
   `s1={12,34,23,56,78,45}`\
   `s2=s1.copy()                     # s2={12,34,23,56,78,45}`<br>
9. **.intersection(set):** Returns a new set with common items from both the sets\
   \
   `s1={12,34,23,56,78,45}`\
   `s2={1,2,34,56,78,9,11}`\
   `s1.intersection(s2)                # {34,56,78}`<br>
10. **.difference():** Returns a new set with the items in the first set but not in the second.\
    \
    `s1={12,34,23,56,78,45}`\
    `s2={1,2,34,56,78,9,11}`\
    `s1.difference(s2)                    # {12,23,45}`<br>
11. **.symmetric\_difference():** Returns a new set with uncommon items from both sets.\
    \
    `s1={12,34,23,56,78,45}`\
    `s2={1,2,34,56,78,9,11}`\
    `s1.symmetric_difference(s2)             # {12,23,45,1,2,9,11}`
