# Python Program to test if the String only Numbers and Alphabets

• Last Updated : 02 Feb, 2021

Given a String, our task is to write a Python program to check if string contains both numbers and alphabets, not either nor punctuations.

Examples:

```Input : test_str = 'Geeks4Geeks'
Output : True
Explanation : Contains both number and alphabets.

Input : test_str = 'GeeksforGeeks'
Output : False
Explanation : Doesn't contain number.```

Method #1 : Using isalpha() + isdigit() + any() + all() + isalnum()

In this, we check for all digits containing is alphabets and numbers combination using all(), isalpha() and isdigit(). The any() and isalnum() is used to filter out possibility of punctuations.

## Python3

 `# Python3 code to demonstrate working of``# Test if string contains both Numbers and Alphabets only``# Using isalpha() + isdigit() + any() + all() + isalnum()`` ` `# initializing string``test_str ``=` `'Geeks4Geeks'`` ` `# printing original string``print``(``"The original string is : "` `+` `str``(test_str))`` ` `# conditional combination for getting result.``res ``=` `not` `((``all``(idx.isdigit() ``for` `idx ``in` `test_str) ``or` `(``all``(idx.isalpha() ``            ``for` `idx ``in` `test_str)) ``or` `(``any``(``not` `idx.isalnum() ``for` `idx ``in` `test_str))))`` ` `# printing result``print``(``"Does string contain both numbers and alphabets only? : "` `+` `str``(res))`

Output:

```The original string is : Geeks4Geeks
Does string contain both numbers and alphabets only? : True```

Method #2 : Using regex

Using regex is one of the ways in which this problem can be solved.

## Python3

 `# Python3 code to demonstrate working of``# Test if string contains both Numbers and Alphabets only``# Using regex``import` `re`` ` `# initializing string``test_str ``=` `'Geeks4Geeks'`` ` `# printing original string``print``(``"The original string is : "` `+` `str``(test_str))`` ` `# conditional combination for getting result.``res ``=` `bool``(re.match(``"^(?=.*[a-zA-Z])(?=.*[\d])[a-zA-Z\d]+\$"``, ``"A530"``))``         ` `# printing result``print``(``"Does string contain both numbers and alphabets only? : "` `+` `str``(res))`

Output:

```The original string is : Geeks4Geeks
Does string contain both numbers and alphabets only? : True```
