# Python code to demonstrate
# to get characters from string
import re
  
# initialising string
ini_string = "123()#$ABGFDabcjw"
ini_string2 = "abceddfgh"
  
# printing strings
print ("initial string : ", ini_string, ini_string2)
  
# code to find characters in string
res1 = " ".join(re.split("[^a-zA-Z]*", ini_string))
res2 = " ".join(re.split("[^a-zA-Z]*", ini_string2))
  
# printing resultant string
print ("first string result: ", str(res1))
print ("second string result: ", str(res2))

                        filter_none








Output: 


        
          
          
          
        

            

initial string :  123()#$ABGFDabcjw abceddfgh
first string result:   ABGFDabcjw
second string result:  abceddfgh


 

Method #2: Using re.fidall











                                    filter_none




                                    edit

                                    close




                                    play_arrow




                                    link

                                    brightness_4

                                    code
                                




















# Python code to demonstrate 


# to get characters in string 


import re 


  


# initialising string 


ini_string = "123()#$ABGFDabcjw"


ini_string2 = "abceddfgh"


  


# printing strings 


print ("initial string : \n", ini_string, "\n", ini_string2) 


  


# code to find characters in string 


res1 = " ".join(re.findall("[a-zA-Z]+", ini_string)) 


res2 = " ".join(re.findall("[a-zA-Z]+", ini_string2)) 


  


# printing resultant string 


print ("first string result: ", str(res1)) 


print ("second string result: ", str(res2)) 



















                        chevron_right







                        filter_none








Output: 


initial string : 
 123()#$ABGFDabcjw 
 abceddfgh

first string result:  ABGFDabcjw
second string result:  abceddfgh


 

Method #3: Using isalpha()











                                    filter_none




                                    edit

                                    close




                                    play_arrow




                                    link

                                    brightness_4

                                    code
                                




















# Python code to demonstrate 


# to get characters in a string 


# if present 


  


# initialising string 


ini_string = "123()#$ABGFDabcjw"


  


# printing string and its length 


print ("initial string : ", ini_string) 


  


# code to find characters in string 


res1 = "" 


for i in ini_string: 


    if i.isalpha(): 


        res1 = "".join([res1, i]) 


  


  


# printing resultant string 


print ("first result: ", str(res1))

                        filter_none








Output: 


initial string :  123()#$ABGFDabcjw
first result:  ABGFDabcjw
