A code to add multiple numbers using Python programming.
Welcome to the code! Here’s a slightly advance code to understand and have fun with tuples using functions in python programming.
In this code, we are defining a function onehop(). The function works like this. It takes as input a list of pairs. It the list of pairs contain (i,j) and (j,k), the function must group them as (i,j).
For example,
onehop([(2,3),(1,2)]) is [(1, 3)]. Similarly, onehop([(2,3),(1,2),(3,1),(1,3),(3,2),(2,4),(4,1)]) is
[(1, 2), (1, 3), (1, 4), (2, 1), (3, 2), (3, 4), (4, 2), (4, 3)].
For this code, we will be using the concept of a function for defining the given function. “not in” operator is used to check if an element is present or not present in the list.

def onehop(l):
nw = []
l.sort()
for i in range(len(l)):
for j in range(len(l)):
if l[i] != l[j]:
if l[i][1] == l[j][0]:
a = l[i][0]
b = l[j][1]
if a != b:
t = [a, b]
t = tuple(t)
if t not in nw:
nw = nw + [tuple(t)]
nw.sort()
return (nw)
l = []
li = input("Enter the group of two tuples:\n") # for taking an input of tuples from the user
while (li != ""):
l.append(tuple(li.split()))
li = input()
print(onehop(l))
Output:
