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



Method # 1: Using a comprehension list + tuple () + str () + expression generator
A combination of the above functions can be used to accomplish this task. In this, we extract each element of the tuple using a generation expression and perform the conversion using str (). Iterate for each tuple by comprehending the list.

# Python3 code to demonstrate how it works
# Convert mixed list of tuples to list of strings
# use comprehension list + tuple () + str () + generator expression

 
# initialize the list

test_list = [( `gfg` , 1 , True ), ( ` is` , False ), ( `best`  , 2 )]

 
# print original list

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

  
# Convert mixed list of tuples to list of strings
# use comprehension list + tuple () + str () + generator expression

res = [ tuple ( str (ele) for ele in sub) for sub in test_list]

 
# print result

print ( " The tuple list after conversion: " + str (res))

Output:

 The original list: [(`gfg`, 1, True), (` is`, False), (`best`, 2)] The tuple list after conversion: [(` gfg`, `1`,` True`), (` is`, `False`), (` best`, `2`)] 

Method # 2: Using map () + tuple () + str ( ) + List Comprehension
A combination of the above functions can be used to accomplish this task. In this we accomplish the task performed by the generator expression above using map ().

# Python3 code to demonstrate how it works
# Convert a mixed list of tuples to a list of strings
# using map () + tuple () + str () + list comprehension

 
# initialize the list

test_list = [( `gfg` , 1 , True ), ( `is` , False ), ( `best` , 2 )]

 
# print original list

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

 
# Convert mixed list of tuples to list of strings
# using map () + tuple () + str () + list comprehension

res = [ tuple ( map ( str , sub)) for sub in test_list]

  
# print result

print ( "The tuple list after conversion:" + str (res))

Output:

 The original list: [(`gfg`, 1, True), (` is`, False), (`best`, 2)] The tuple list after conversion: [(`gfg`,` 1`, `True`), (` is`, `False`), (` best`, `2`)]
