把数字转换成LCD显示模式
''' Python小练习(001):
把数字(0~9)转换成LCD显示的模式。
例如:0: 1: 2: 3: 4: 5: 6: 7: 8: 9:
_ _ _ _ _ _ _ _
|| | _| _| |_| |_ |_ | |_| |_|
|_| | |_ _| | _| |_ | |_| _|
如果输入数字: 1234, 输出:
_ _
| _| _| |_|
| |_ _| |
'''
思路根据LCD特性,分为3层,可以使用list,dict形式来存储每特性
代码:
lcd={0:[' _','| | ','|_| '],\
1:[' ','| ','| '],\
2:[' _',' _| ','|_'],\
3:[' _',' _| ',' _| '],\
4:[' ','|_| ','| '],\
5:[' _','|_',' _| '],\
6:[' _','|_','|_| '],\
7:[' _','| ','| '],\
8:[' _','|_| ','|_| '],\
9:[' _','|_| ',' _| ']}
def number2lcd(n):
global lcd
output = [' ',' ',' ']
l = len(str(n))
while True:
i = n // 10 **(l-1)
for j in range(3):
output += lcd
n = n%10**(l-1)
l -=1
if 1==0:
break
return output
n = int(raw_intput('Input the numbers:'))
output = number2lcd(n)
for each in output:
print each
