range-Funktion¶

Ziffern 1 bis 10 als Liste¶

liste = range(1,10)
print(liste)
for i in liste:
    print(i, end=', ')

>>> 1, 2, 3, 4, 5, 6, 7, 8, 9,

Großbuchstaben als Liste¶

import string

for buchstabe in string.ascii_uppercase:
    print(buchstabe, end=', ')

>>> A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z,
