Python | Convert String to list of tuples
Sometimes, while working with data, we can have a problem in which we have a string list of data and we need to convert the same to list of records. This kind of problem can come when we deal with a lot of string data. Let’s discuss certain ways in which this task can be performed.
Method #1 : Using zip() + split() + list slicing
The combination of above functionalities can be used to solve this problem. In this, first, the string is converted to list of strings and then required tuples are made using zip() and list slicing functionality.
# Python3 code to demonstrate working of # Convert String to list of tuples # Using zip() + list slicing + split() # initialize string test_string = "GFG is best Computer Science Portal" # printing original string print("The original string : " + str(test_string)) # Convert String to list of tuples # Using zip() + list slicing + split() temp = test_string.split() res = list(zip(temp[::2], temp[1::2])) # printing result print("List after String to tuple conversion : " + str(res)) |

Output :
The original string : GFG is best Computer Science Portal
List after String to tuple conversion : [(‘GFG’, ‘is’), (‘best’, ‘Computer’), (‘Science’, ‘Portal’)]
Method #2 : Using iter() + split() + next() + generator expression
This is yet another method to perform this particular task. In this, we use iterator to reach to solution of this task. Method is same as above, just iterator is used for faster access.
# Python3 code to demonstrate working of # Convert String to list of tuples # Using iter() + split() + next() + generator expression # initialize string test_string = "GFG is best Computer Science Portal" # printing original string print("The original string : " + str(test_string)) # Convert String to list of tuples # Using iter() + split() + next() + generator expression temp = iter(test_string.split()) res = [(ele, next(temp)) for ele in temp] # printing result print("List after String to tuple conversion : " + str(res)) |

Output :
The original string : GFG is best Computer Science Portal
List after String to tuple conversion : [(‘GFG’, ‘is’), (‘best’, ‘Computer’), (‘Science’, ‘Portal’)]
