Method # 1: Using re.split
| # Python code for demo
# to get characters from a string import re
# initialization string ini_string = "123 () # $ ABGFDabcjw" ini_string2 = "abceddfgh"
# print lines print ( "initial string:" , ini_string, ini_string2)
# code to find characters in a string res1 = "" . join (re.split ( "[^ a-zA-Z] *" , ini_string)) res2 = "" . join (re. split ( "[^ a-zA-Z] *" , ini_string2))
# print the resulting string print ( "first string result:" , str (res1)) print ( "second string r esult: " , str (res2)) |
Exit:
initial string: 123 () # $ ABGFDabcjw abceddfgh first string result: ABGFDabcjw second string result: abceddfgh
Method # 2: Using re.fidall
| # Python code for demonstration
# to get characters in a string import re
# initializing string ini_string = "123 () # $ ABGFDabcjw" ini_string2 = " abceddfgh "
# print lines print ( "initial string:" , ini_string, "" , ini_string2)

# print the resulting string print ( "first string result:" , str (res1)) print ( "second string result:" , str (res2)) |
Exit:
initial string: 123 () # $ ABGFDabcjw abceddfgh first string result: ABGFDabcjw second string result: abceddfgh
Method # 3: Using isalpha()
| # Python code for demonstration
# to get characters in a string
# if you present
# initialization string ini_string = "123 () # $ ABGFDabcjw"
# print line and its length print ( "initial string:" , ini_string)
# code to find characters in a string res1 = "" for i in ini_string: if i.isalpha (): res1 = "". join ([res1, i])
# print the resulting string print ( "first result:" , str (res1)) |
Exit :
initial string: 123 () # $ ABGFDabcjw first result: ABGFDabcjw
