How we can iterate through list of tuples in Python
In this article, we will discuss different ways to iterate the list of tuples in Python.
It can be done in these ways:
- Using Loop.
- Using enumerate().
Method 1: Using Loop
Here we are going to form a list of tuples using for loop.
Python3
# create a list of tuples with student# detailsname = [('sravan',7058,98.45), ('ojaswi',7059,90.67), ('bobby',7060,78.90), ('rohith',7081,67.89), ('gnanesh',7084,98.01)]# iterate using for loopfor x in name: # iterate in each tuple element for y in x: print(y) print() |
Output:
sravan 7058 98.45 ojaswi 7059 90.67 bobby 7060 78.9 rohith 7081 67.89 gnanesh 7084 98.01
Method 2: Using enumerate()
Here we are going to use enumerate() function to Iterate the list of tuples. A lot of times when dealing with iterators, we also get a need to keep a count of iterations. Python eases the programmers’ task by providing a built-in function enumerate() for this task. Enumerate() method adds a counter to an iterable and returns it in a form of enumerate object. This enumerate object can then be used directly in for loops or be converted into a list of tuples using list() method.
Syntax: enumerate(iterable, start=0)
Parameters:
- Iterable: any object that supports iteration
- Start: the index value from which the counter is to be started, by default it is 0
Python3
# create a list of tuples with student# detailsname = [('sravan',7058,98.45), ('ojaswi',7059,90.67), ('bobby',7060,78.90), ('rohith',7081,67.89), ('gnanesh',7084,98.01)]l = []# iterate using index with enumerate functionfor index, tuple in enumerate(name): # access through index # by appending to list l.append(name[index]) # iterate through the listfor x in l: for y in x: print(y) print() |
Output:
sravan 7058 98.45 ojaswi 7059 90.67 bobby 7060 78.9 rohith 7081 67.89 gnanesh 7084 98.01
