Python | Convert a list of tuples of mixed data types to a list of strings

Learn examples from DataCamp guru:

Method # 1: Using split () + join ()
This is one way we can accomplish this task. In this, we break the elements apart and then return the last value and add a new element using join ().

# Python3 code to demonstrate how it works
# Replace the trailing word in the line
# using split () + join ()

# initialization string

test_str = " GFG is good "

# print original line

print ( "The original string is:" + test_str)

# initialize string replacement

rep_str = "best"

# Replace the backword in the line
# using split () + join ()

res = "" . join (test_str.split ( `` ) [: - 1 ] + [rep_str ])


  
  # print result  
  print   (  "The String after performing replace:"   +   res)

Output:

 The original string is: GFG is good The String after performing replace: GFG is best

Method # 2: Using rfind () + join ()
A combination of these functions can also be used to accomplish this task. In this we perform the task of extracting the last word of a string using rfind () and join () is used to perform the replacement.

# Python3 code to demonstrate how it works # Replace the backword in the line # using rfind () + join ()


  
  # initialization string  
  test_str   =  " GFG is good " 
   
  # print original line  
  print   (  "The original string is:"   +   test_str) 
   
  # initialize string replacement  
  rep_str   =   "best"  
  
  # Replace the backword in the line  
  # using rfind () + join ()  
  res   =   test_str [: test_str.rfind ( ` ` )]   +  ` `  +   rep_str 
  
  # print result  
  print   (  "The String after performing replace:"   +   res)

Output:

 The original string is: GFG is good The String after replace: GFG is best performing
