python - upper() case of number key -

i'm trying implement input box in pygame. i've gotten point can input text in lower , upper case letters (shift changes upper case, usual). checking whether l_shift/r_shift pressed , if is, use char = char.upper() turn char corresponds pressed key corresponding upper char. works fine letters (a-z -> a-z). not work numbers , other special symbols 1 -> !, 2 -> ", . -> : or , -> ; (german keyboard layout).

is there better way in python turn chars corresponding shift+key chars?

there no inherent mapping numbers punctuation marks associated them on keyboard, you'll have specify them yourself. use map, this:

number_map = {   '1':'!',   '2':'@',   '3':'#',   #etc   #etc }  print(number_map['1']) # print ! 

this nice because can use other non-alphabetic keys.
