Ok here is my version of doing this  I noticed that you want your output to be 7  which means you dont want to count special characters and numbers  So here is regex pattern   re findall   a-zA-Z      string    Where  a-zA-Z   means it will match any character beetwen a-z  lowercase  and A-Z  upper case       About spaces  If you want to remove all extra spaces  just do   string   string rstrip   lstrip     Remove all extra spaces at the start and at the end of the string while      in string    While  there are 2 spaces beetwen words in our string        string   string replace                  replace them by one space

str split   without any arguments splits on runs of whitespace characters    gt  gt  gt  s    I am having a very nice day    gt  gt  gt    gt  gt  gt  len s split    7   From the linked documentation      If sep is not specified or is None  a different splitting algorithm is applied  runs of consecutive whitespace are regarded as a single separator  and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace
