Python | Convert string representation of list to list

|

Method # 1: Using split () and strip()

# Python code to demonstrate conversion
# string representation of list to list
# using stripe and splitting

 
# initialize the inline view of the list

ini_list = "[1, 2, 3, 4, 5] "

  
# print the initialized list string and its type

print ( "initial string" , ini_list)

print ( type (ini_list))

 
# Convert string to list

res = ini_list.strip ( ’] [’ ). split ( ’,’ )

 
# print the final result and its type

print ( "final list" , res)

print ( type (res))

Exit:

 initial string [1, 2, 3, 4, 5] "class ’str’" final list [’1’,’ 2’, ’3’,’ 4’, ’5’] "class’ list’" 

Method # 2: Using ast.literal_eval()

# Python code to demonstrate conversion
# string representation of list to list
# using ast.literal_eval ( )

import ast

  
# initialize the inline view of the list

ini_list = "[1, 2, 3, 4, 5]"

 
# print the initialized list string and its type

print ( "initial string" , ini_l ist)

print ( type (ini_list))

 
# Convert string to list

res = ast.literal_eval (ini_list)

 
# print the final result and its type

print ( "final list" , res)

print ( type (res))

Exit :

 initial string [1, 2, 3, 4, 5] "class ’str’" final list [1, 2, 3, 4, 5] "class ’list’" 

Method # 3: Using json.loads()

# Python code to demonstrate conversion
# string representation of list to list
# using json.loads ( )

import json

  
# initialize the inline view of the list

ini_list = "[1, 2, 3, 4, 5]"

 
# print the initialized list string and its type

print ( "initial string" , ini_list)  

print ( type (ini_list))

 
# Convert string to list

res = json.loads (ini_list)

 
# print the final result and its type

print ( "final list" , res)

print ( type (res))

Exit :

 initial string [1, 2, 3, 4, 5] "class ’str’" final list [1, 2, 3, 4, 5] "class ’list’"
