#sets are unordered , unchangeable , unindexed
#sets are unordered so this means in what order they could appear
# sets are unchangeable but we can add or remove items.

# duplicates are not aloowed in sets

# a = {"apple", "apple"}
# print(a)

# in sets true and 1 are considered as same and duplicates

# a = {True,1}
# print(a)

#in sets flase and 0  are considered as same and duplicates

# a = {False,0}
# print(a)

# we can use set() constructor to construct a set using double brackets

# a = set(("apple"))
# print(a)

# access items using for loop

# a = {"apple" , "banana"}
# for x in a :
#   print(x)

# a= "5"
# b = "5"
# print(a+b)

# x = 'hello'
# y = x.upper()
# print(x,y)

# for a in range(len(x)):
#   x[a] = x[a].upper()

# print(x)
