Python program to iterate over multiple lists simultaneously?
Here we use .zip() for iterative over multiple lists simultaneously.zip() takes n number of iterables and returns list of tuples. i-th element of the tuple is created using the ith element from each of the iterables.
Example
L1=[1,2,3,4] L2=[‘aa’,’bb’,’cc’,’dd’] L=zip(L1,L2) Output [(1,’aa’),(2,’bb’),(3,’cc’),(4,’dd’)]
Algorithm
Step 1: first create 3 user input list. Step 2 : use .zip() function. Step 3: print tuples.
Example code
# To iterate over 3 lists using zip function
importitertools
A=list()
B=list()
C=list()
n = int(input("How many you data want to store??"))
print("Enter Roll no.")
for i in range(int(n)):
k=int(input(""))
A.append(k)
print("Enter Name ::")
for j in range(int(n)):
k1=input("")
B.append(k1)
print("Enter Age ::")
for j in range(int(n)):
k1=int(input(""))
C.append(k1)
print ("\niterating using zip")
for (a, b, c) in zip(A, B, C):
print (a, b, c)
Output
How many you data want to store??4 Enter Roll no. 56 89 67 34 Enter Name :: yui jkl vm dfg Enter Age :: 7 9 6 5 iterating using zip 56 yui 7 89 jkl 9 67 vm 6 34 dfg 5
