Python get first element of tuple | Example code – EyeHunts – Tutorial
Use indexing to get the first element of each tuple. Use a for-loop to iterate through a list of tuples. Within the for-loop, use the indexing tuple[0] to access the first element of each tuple, and append it. tuple_list = [(a, b), (c, d)] ele = [] for x in tuple_list: ele.append(x[0]) print(ele) Output: [‘a’, ‘c’]

tup() returns a 2-tuple. In order to solve i = 5 + tup() # I want to add just the three you select the 3 by: tup()[0] # first element so all together: i = 5 + tup()[0] Alternatives. Go with namedtuple that allows you to access tuple elements by name (and by index). Details are at https://docs.python.org/3/library/collections.html#collections.namedtuple
