Python | Convert a list of strings to a sorted list of integers

|

Examples :

  Input:  [’21’,’ 1’, ’131’,’ 12’, ’15’]  Output:  [1, 12, 15, 21, 131]  Input:  [’11’,’ 1’, ’58’,’ 15’, ’0’]  Output:  [0, 1, 11, 15, 58] 

Let’s discuss the various methods we can use to accomplish this task.

Method # 1: Using map and sorted()

# Python code for list conversion
# string in a sorted list of integers

 
# Initialization list

list_string = [ ’21’ , ’1’ , < / code> ’131’ , ’ 12’ , ’15’ ]

  
# display

list_map = map ( int , list_string)

 
# sorting the list

list_sorted = sorted (list_map)

 
# Prints a sorted list of integers

print (list_sorted)

< / code> Exit :

 [1, 12, 15, 21, 131] 

Method # 2: Using a list understanding

# Python code to convert the list
# string in a sorted list of integers

 
# Initialization list

list_string = [ ’11’ , ’1’ , ’58’ , ’ 15’ , ’0’ ]

  
# Using the comprehension list i

output = [ int (x) for x in list_string]

 
# using the sort function
output.sort ()

 
# Printout

print (output)

Output:

 [0, 1, 11, 15, 58] 

Method # 3: Using iteration

# Python code to convert the list
# string in a sorted list of integers

 
# Initialization list

list_string = [ ’ 11’ , ’1’ , ’58’ , ’ 15’ , ’ 0’ ]

  
# using iteration and sorting ()

list_sorted = sorted ( int (x) for x in list_string)

 
# print output

print (list_sorted)

Exit :

 [0, 1, 11, 15, 58]
