Python String : isalpha()


This article demonstrates how to use of isalpha() method in string.

The isalpha() method returns True if all characters in the string are alphabets. If not, it returns False.


Syntax :

string.isalpha()


Parameter Values :

The isalpha() doesn't take any parameters.

Returns :

The isalpha() returns:

  • True if all characters in the string are alphabets (can be both lowercase and uppercase).
  • False if at least one character is not alphabet.


Sample Code :

1.
string = "Cppsecrets"
print(string.isalpha())

# contains whitespace
string = "cpp secrets "
print(string.isalpha())

string = "CppSecrets123"
print(string.isalpha())

string = "133"
print(string.isalpha())
Output :
True                                                                                                                                          
False                                                                                                                                         
False                                                                                                                                         
False

2.
string = "CppSecrets"

if string.isalnum() == True:
   print("All characters are alphabets.")
else:
    print("All characters are not alphabets.")
Output :
All characters of are alphabets.


Hence,we can see above function isalpha() returns true if string has at least 1 character and all characters are alphabetic and false otherwise.
