【Time系列五】个性时钟与秒表升级版

从昨天到现在，一直在研究这个看起来超级简单的时钟。界面非常简洁大方。

虽然是简单，可是这个对齐的问题还是把我整得一塌糊涂。谁叫作者不解释清楚的。

参考:http://bbs.fishc.com/thread-77638-1-1.html

接下来，我们一步步解决。

----------------------------------------------------------------------------------------------------------------

步骤1

注意。这里是换行打印才能打印出这种图形的，这个字典储存的是列表，为啥储存的是列表呢？因为待会

一个数字，我们是要分上中下三个部分打印的。

这里的元素要尽可能对齐，因为这个程序最麻烦的就是要整齐的输出。第一个/位置0元素的笔画统一居中。

以0为例，位置0(一横)除了1和4之外,在其它数字都是给包围起来的，所以两边的空格其实是留给竖的！！!

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

 for num in lcd:
     for i in lcd[num]:
         print i

如果输出的是这种整整齐齐的数字的话(代码是纵向输出的)，说明我们千辛万苦输入的列表元素是正确的。

步骤2

    接上面的代码，完整版在下面。

 # coding: utf-8                                                             

 import time

 # 分别把时，分，秒，拆分成上中下三个部分并
 # 分别存储到一个空列表中(empty)

 def num2lcd(time):
    et = ["", "", ""]
    shiwei = time / 10
    gewei = time % 10

    for i in range(0, 3):
        et[i] = lcd[shiwei][i] + lcd[gewei][i]

    return et

 # time.localtime()是输出当前日期的元组
 # t.tm_hour是时，t.tm_min是分钟
 # 这个函数最关键的部分是把之前分开的时，
 # 分，秒的列表元素集合到一个列表中，最后统一打印出来。

 def clock():
     t = time.localtime()
     h = num2lcd(t.tm_hour)
     m = num2lcd(t.tm_min)
     s = num2lcd(t.tm_sec)

     output = [h[0] + m[0] + s[0], h[1] + m[1] + s[1], h[2] + m[2] + s[2]]
     return output

注意，这里的时间显示能否对齐完全取决于lcd字典是否对齐，每个值前面和后面的空格数量一定要控制好

---------------------------------------------------------------------------------------------------------------------------

 # coding: utf-8                                                                                   2016/12/8

 import os, time

 # 这里在上面的基础上，每个列表的元素后面加
 # 多一个空格，让数字之间显示更美观

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

 # 分别把时，分，秒，拆分成上中下三个部分并
 # 分别存储到一个空列表中(empty)

 def num2lcd(time):
    et = ["", "", ""]
    shiwei = time / 10
    gewei = time % 10

    for i in range(0, 3):
        et[i] = lcd[shiwei][i] + lcd[gewei][i]

    return et

 # time.localtime()是输出当前日期的元组
 # t.tm_hour是时，t.tm_min是分钟
 # 这个函数最关键的部分是把之前分开的时，
 # 分，秒的列表元素集合到一个列表中，最后统一打印出来。

 def clock():
     t = time.localtime()
     h = num2lcd(t.tm_hour)
     m = num2lcd(t.tm_min)
     s = num2lcd(t.tm_sec)

     output = [h[0] + " " + m[0] + " " + s[0], h[1] + "." + m[1] + "." + s[1], h[2] + "." + m[2] + "." + s[2]]
     return output

 while True:
     for i in clock():
         print i
     time.sleep(1)
     os.system("cls")

时钟完整版

由于在时和分，分和秒之间加了冒号，而每个时h[0]和分m[0]，分m[0]和秒s[0]之间距离是一定的，

由于冒号自身占用1个空格，所以后面的会变成这样。因此要在h[0]的m[0]，m[0]和s[0]之间加上空格。

 output = [h[0] + " " + m[0] + " " + s[0], h[1] + "." + m[1] + "." + s[1], h[2] + "." + m[2] + "." + s[2]]

秒表的同理类似。这里就不再介绍了，直接附上代码。

# coding: utf-8

import os, sys, time

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

def num2lcd(time):
    et = ["", "", ""]
    shiwei = time / 10
    gewei = time % 10

    for i in range(0, 3):
        et[i] = lcd[shiwei][i] + lcd[gewei][i]

    return et

def clock(minute, second):
    m = num2lcd(minute)
    s = num2lcd(second)

    output = [m[0] + " " + s[0], m[1] + "." + s[1], m[2] + "." + s[2]]

    return output

sec = 0
while True:
        sec += 1
        m = sec / 60
        s = sec % 60

        for i in clock(m, s):
            print i

        time.sleep(1)
        os.system("cls")

一般来说，当需要输出时间时，用求余符号%来求出分和秒是比较简便的。或者大家也可

以看看下面这一种。是用for循环在1和60之间循环递增的。选择自己喜欢的一种即可。

 # coding: utf-8

 import os, sys, time

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

 def num2lcd(time):
     et = ["", "", ""]
     shiwei = time / 10
     gewei = time % 10

     for i in range(0, 3):
         et[i] = lcd[shiwei][i] + lcd[gewei][i]

     return et

 def clock(minute, second):
     m = num2lcd(minute)
     s = num2lcd(second)

     output = [m[0] + " " + s[0], m[1] + "." + s[1], m[2] + "." + s[2]]

     return output

 minute = 0
 while True:
     for sec in range(1, 61):
         if sec == 60:
             sec = 0                       # 记得到了第60秒时秒要清零哦
             minute += 1                   # 同时分钟要 +1

         for i in clock(minute, sec):
             print i

         time.sleep(1)
         os.system("cls")
