You shouldn t be setting x       That is setting an empty list to your inputted parameter  Furthermore  use python s for i in x syntax as follows   for i in x      if i isalpha            letters  1     elif i isnumeric            digit  1     elif i isspace            space  1     else          other  1

There are 2 errors is this code   1  You should remove this line  as it will reqrite x to an empty list   x        2  In the first  if  statement  you should indent the  letter    1  statement  like   if x i  isalpha        letters    1

Ignoring anything else that may or may not be correct with your  revised code   the issue causing the error currently quoted in your question is caused by calling the  count  function with an undefined variable because your didn t quote the string    count thisisastring222  looks for a variable called thisisastring222 to pass to the function called count  For this to work you would have to have defined the variable earlier  e g  with thisisastring222    AStringWith1NumberInIt    then your function will do what you want with the contents of the value stored in the variable  not the name of the variable  count  thisisastring222   hardcodes the string  thisisastring222  into the call  meaning that the count function will work with the exact string passed to it    To fix your call to your function  just add quotes around asdfkasdflasdfl222 changing count asdfkasdflasdfl222  to count  asdfkasdflasdfl222     As far as the actual question  How to count digits  letters  spaces for a string in Python   at a glance the rest of the  revised code  looks OK except that the return line is not returning the same variables you ve used in the rest of the code  To fix it without changing anything else in the code  change number and word to digit and letters  making return number word space other into return digit letters space other  or better yet return  digit  letters  space  other  to match current behavior while also using better coding style and being explicit as to what type of value is returned  in this case  a tuple
