How to use a simple for loop In Python

This code initializes an empty string res and iterates through each tuple in the list test_list. For each tuple, it adds the first and last name to res, along with a comma and space. Finally, it removes the last comma and space from res. The result is the same as the one obtained using the map() and join() methods.

Python3

# Initializing list
test_list = [('Manjeet', 'Singh'), ('Nikhil', 'Meherwal'), ('Akshat', 'Garg')]
 
# printing original list
print("The original list is : " + str(test_list))
 
# Convert tuple records to a single string using a for loop
res = ""
for tuple in test_list:
    res += tuple[0] + " " + tuple[1] + ", "
 
# remove the last comma and space
res = res[:-2]
 
# printing result
print("The string after tuple conversion: " + res)

Output

The original list is : [('Manjeet', 'Singh'), ('Nikhil', 'Meherwal'), ('Akshat', 'Garg')]
The string after tuple conversion: Manjeet Singh, Nikhil Meherwal, Akshat Garg

Time complexity: O(n), where n is the number of tuples in the test_list.
Auxiliary space: O(m), where m is the length of the resulting string res.
