how can I find and print the content of an attribute by a given number?-CodePudding

So the program works like this, i need to input a number and once my program identifies the number in the class it will print the given number in LCD format (7-segment display).

class lcd:
  def numbers():
    0 = ["_","| |","_"]
    1 = ["|","|","|"]
    2 = ["_","_|","|_"]
    3 = ["_","_|","_|"]
    4 = ["|_|"," |"]
    5 = ["_","|_"," _|"]
    6 = ["_","|_","|_|"]
    7 = ["_"," |"," |"]
    8 = ["_","|_|","|_|"]
    9 = ["  _","|_|"," _|"]

def numgen(num):
  print("Type the number you want to print in LCD: ")
  num = lcd()
  for i in range (lcd):
    if hasattr(num,'numbers'):
      for i in range (3):
        print("\n")
 return  

if __name__ == '__main__':
  num = int(input())
  numgen()
  print(num)

The problem is that I don't know how can I proceed, i've been reading some functions but none of them works. I tried as you can see a weird way with hasattr but obviously it didn't work. In the last loop I tried to print that space for each object in my attributes, so in that way the number will print correctly. I will much appreciate any help.

CodePudding user response：

IIUC, you want to print numbers in LCD format (or rather 7 segments).

Here is a minimal code for it. The most important part is to use zip to build the lines.

NB. I had to fix your digit segments that were incorrect.

digits = {
    0 : [" _ ","| |","|_|"],
    1 : [" ","|","|"],
    2 : [" _ "," _|","|_ "],
    3 : ["_ ","_|","_|"],
    4 : ["   ", "|_|","  |"],
    5 : [" _ ","|_ "," _|"],
    6 : [" _ ","|_ ","|_|"],
    7 : ["_ "," |"," |"],
    8 : [" _ ","|_|","|_|"],
    9 : [" _ ","|_|"," _|"],}

def print_num(num):
    parts = [digits[int(d)] for d in str(num)]
    print('\n'.join(' '.join(line) for line in zip(*parts)))
    
print_num(1234567890)

Output:

   _  _       _   _  _   _   _   _ 
|  _| _| |_| |_  |_   | |_| |_| | |
| |_  _|   |  _| |_|  | |_|  _| |_|
