How to convert value to defined number?

[philipbergwerf]

Yeah the problem is solved! Thankyou Larz60+!

the solution was this:

# User input
rightNotes = "c4 e4 g4 c5"
# Convert user input to numbers
text2Numbers = {'c4': 40, 'e4': 44, 'g4': 47, 'c5': 52}
rightNumbers = [] # input for my program!
for pitch in rightNotes.split():
    rightNumbers.append(text2Numbers[pitch])
print(rightNumbers)
