Python | Convert tuple records to one string

Method # 1: Using join () + list comprehension
In this method, we simply iterate over the elements of the list tuple and perform a space-separated join between them. to concatenate them as one row of records.

# Python3 code to demonstrate how it works
# Convert single line tuple entries
# Using list comprehension + join ()

 
# Initializing list

test_list = [( `Manjeet` , `Singh` ), ( ` Nikhil` , `Meherwal` ), ( ` Akshat` , `Garg` )]

  
# print original list

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

 
# Convert tuple entries to one line
# Using list comprehension + join ()

res = `,` . join ([ `` . join (sub) for sub in test_list])

  
# print 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  
 
  Method # 2: Using  map () + join ()   
 This method performs this task in a similar way to the above function. The only difference is that it uses  map ()  to extend the connection logic, not to comprehend the list. 
 
 
 
  
  
  
  # Python3 code to demonstrate how it works  
  # Convert tuple entries to one line  
  # Using map () + join ( )  
 
  
  # Initializing list  
 
  test_list   =   [(  ` Manjeet`  ,   `Singh`  ), (  `Nikhil`  ,  ` Meherwal`   ), (  `Akshat`  ,   `Garg`  )] 
 
   
  # print original list  
 
  print   (  "The original list is:"   +   str   (test_list)) 
 
  
  # Convert tuple entries to one line  
  # Using map () + join ()  
 
  res   =   `,`  . join (  map   (  ""  . join, test_list))   
  
  # print result  
 
  p rint   (  "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
