To grep for a pattern in the directory of the active buffer:

   M-x grep
   Run grep (like this): grep -nH -e 

Complete the grep command:

   Run grep (like this): grep -nH -e class *.py

and hit ENTER. Feel free to modify the command from grep to egrep, for
example. I often replace -e with -i.

To grep for a pattern in any subdirectory:

   M-x grep
   Run grep (like this): grep -nH -r assert .

or:

   M-x grep-find
   Run find (like this): find . -type f -exec grep -nH -e assert {} +

Again, you can modify the command freely:

   M-x grep-find
   Run find (like this): find . -name '*.py' -exec grep -nH -e assert {} +

You will get a list of hits in a new buffer. You can use the C-x `
command to traverse them in order, but there are many other ways.
