Python | Convert string to list of tuples

|

Method # 1: Using zip () + split () + list slicing
A combination of the above functions can be used to solve this problem. This first converts the string to a list of strings, and then creates the necessary tuples using the zip () function and slicing the list.

# Python3 code to demonstrate how it works
# Convert string to list of tuples
# Using zip () + slicing list + split ()

 
# initialize string

test_string = "GFG is best Computer Science Portal"

 
# print original line

print ( "The original string:"  + str (test_string))

 
# Convert string to a list of tuples
# Using zip () + slicing the list + split ()

temp = test_string.split ()

res = list ( zip (temp [:: 2 ], temp [ 1 :: 2 ]))

 
# print result

print ( "List after S tring 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 more one method to accomplish this specific task. In this we use an iterator to achieve a solution to this problem. The method is the same as above, just an iterator is used for faster access.

# Python3 code to demonstrate how it works
# Convert string to list of tuples
# Using iter () + split () + next () + generator expression

 
# initialize string

test_string = " GFG is best Computer Science Portal "

 
# print original line

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]

  
# print 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’)]
