Python3----output all uppercase and lowercase letters and numbers

1. Output all large (small) letters with one line, and numbers

1 Print([Chr (i) forIinchRange (65, 91)])#All uppercase Letters2 Print([Chr (i) forIinchRange (97, 123)])#All lowercase letters3 Print([Chr (i) forIinchRange (48, 58)])#All numbers4 5 ####################6['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']7['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']8['0','1','2','3','4','5','6','7','8','9']

2. Generate Random Verification code

1 Import Random 2 def Get_code (): 3     Source = List ('0123456789')4for in      Range (123):5        source.append (Chr (i))6     print( '. Join (Random.sample (source, 4)))

1 def V_code (): 2     "' 3      for  in range (5):4         add = Random.choice ([Random.randrange], Chr (Random.randrange ( (123)])5         code + = str (add)6     print(code)
