Notes [1] = These operations rely on the "Amortized" part of "Amortized Worst Case". Individual actions may take surprisingly long, depending on the history of the container. [2] = Popping the intermediate element at indexkfrom a list of sizenshifts all elementsafterkby one slot to the l...
both operands must be sets. The.union()method, on the other hand, will take any iterable as an argument, convert it to a set, and then perform the union.
Let us look at the below examples and learn what are the different ways to join or combine two or multiple sets into one set. Using union() function Using update() function Using " | " operator Using reduce() function Using itertools.chain() function ...
def multiple_strings(first, second): # The input of both the strings are given data1 = set(first) # Both the strings are then converted into data sets data2 = set(second) union_data = data1.union(data2) # After conversion, the data sets are combined with the help of union operation...
