Python | Methods for sorting the letters of a string alphabetically



Examples :

  Input:  PYTHON  Output:  HNOPTY  Input:  Geeks  Output:  eeGks 

When a line in the same case —

Method # 1: Using sorted ( ) with join()

# Python3 mail sorting program
Line # alphabetically

 

def sortString ( str ):

return `` .join ( sorted ( str ))

  
# Driver code

str = `PYTHON`

print (sortString ( str ))

Exit:

 HNOPTY 

Method # 2: Using sorted () with accumulate()

# Python3 mail sorting program
Line # in alphabetical order

from itertools import accumulate

  

def < code class = "plain"> sortString ( str ):

return tuple (accumulate ( sorted ( str )) ) [ - 1 ]

 
# Driver code

str = `PYTHON`

print (sortString ( str ))

Exit:

 HNOPTY 

Method # 3: Using sorted () with reduce()

 

Another alternative is to use the redu () method. It applies a join function to the sorted list using the “+” operator.

# Python3 mail sorting program
Alphabetical line #

from functools import reduce

 

def sortString ( str ):

return reduce ( lambda a, b: a + b, sorted ( str ))

  
# Driver code

str = ` PYTHON`

print (sortString ( str ))

Exit:

 HNOPTY 

When the string in different cases —

Using sorted () with join()

# Python3 email sorting program
Line # in alphabetical order

from itertools import accumul ate

 

def sortString ( str ):

  return " ". join ( sorted ( str , key = lambda x: x.lower ()))

 
# Driver code

str = ` Geeks`

print (sortString ( str ))

Exit:

 eeGks
