Python | List of tuples per string



Method # 1: Using str () + strip ()
A combination of the above functions can be used to solve this problem. In this we just convert the list to a string and strip the opening, closing square brackets of the list to represent the string.

# Python3 code to demonstrate how it works
# List of tuples to string
# using str () + strip ()

 
# initialize the list

test_list = [( 1 , 4 ), ( 5 , 6 ), ( 8 , 9 ), ( 3 , 6 )]

 
# print original list

print ( "The original list is:" + str (test_list))

  
# List of tuples per string
# using str () + strip ()

res = str (test_list) .strip ( `[]` )

 
# print result

print ( " Resultant string from list of tuple: " + res)

Output:

 The original list is: [(1, 4), (5, 6), (8, 9), (3, 6)] Resultant string from list of tuple: (1, 4), (5, 6), (8 , 9), (3, 6) 

Method # 2: Using map () + join ()
This is another way to accomplish this task. In this we apply a string conversion function to each element and then join the tuples using join () .

# Python3 code for demonstrations
# List of tuples in a string
# using map () + join ()

 
# initialize the list

test_list = [( 1 , 4 ), ( 5 , 6 ), ( 8 , 9 ), ( 3 , 6 )]

 
# print original list

print ( "The original list is:" + str (test_list))

  
# List of tuples per string
# using map () + join ()

res = "," . join ( map ( str , test_list))

 
# print result

print ( "Resultant string from list of tuple:" + res)

The output:

 The original list is: [(1, 4), (5, 6), (8, 9), (3, 6) ] Resultant string from list of tuple: (1, 4), (5, 6), (8, 9), (3, 6)
