Question

我需要使用月份和日期打印月份。但我似乎无法使用Python将'1'后面的数字移动到下一行。

# This program shows example of "November" as month and "Sunday"  as day.

month = input("Enter the month('January', ...,'December'): ")
day = input("Enter the start day ('Monday', ..., 'Sunday'): ")
n = 1

if month == "January" or month == "March" or month == "May" or month == "July" or month == "August" or month == "October" or month == "December":
        x = 31
elif month == "February":
        x = 28
else:
        x = 30

print(month)
print("Mo Tu We Th Fr Sa Su")
if (day == "Sunday"):
        print("                  ", end='')
for i in range (1, 7):
        for j in range (1, 8):
                while n != x+1:
                        print('%2s' % n, end=' ')
                        n = n + 1
                        break
        print()

输出如下：

November
Mo Tu We Th Fr Sa Su
                   1  2  3  4  5  6  7 
 8  9 10 11 12 13 14 
15 16 17 18 19 20 21 
22 23 24 25 26 27 28 
29 30

Answer 1

一些变化。

没有嵌套循环，只需要一个打印所有日期的循环。然后，在该循环内，决定是否结束该行（如果您刚刚打印的日期对应于星期日）。

此外，每月查找的天数更清晰一些，您现在处理更多＆＃34;天＆＃34;而不仅仅是星期天：

day = "Monday"
month = "March"


# Get the number of days in the months
if month in ["January", "March", "May", "July", "August", "October", "December"]:
    x = 31
elif month in ["February"]:
    x = 28
else:
    x = 30

# Get the number of "blank spaces" we need to skip for the first week, and when to break
DAY_OFF = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']
off = DAY_OFF.index(day)

print(month)
print("Mo Tu We Th Fr Sa Su")
# Print empty "cells" when the first day starts after Monday
for i in range(off):
    print("  ", end=' ')
# Print days of the month
for i in range(x):
    print("%2d" % (i+1), end=' ')
    # If we just printed the last day of the week, print a newline
    if (i + off) % 7 == 6: print()

三月/星期一

March
Mo Tu We Th Fr Sa Su
 1  2  3  4  5  6  7 
 8  9 10 11 12 13 14 
15 16 17 18 19 20 21 
22 23 24 25 26 27 28 
29 30 31

三月/周日

March
Mo Tu We Th Fr Sa Su
                   1 
 2  3  4  5  6  7  8 
 9 10 11 12 13 14 15 
16 17 18 19 20 21 22 
23 24 25 26 27 28 29 
30 31

2月/日

February
Mo Tu We Th Fr Sa Su
                   1 
 2  3  4  5  6  7  8 
 9 10 11 12 13 14 15 
16 17 18 19 20 21 22 
23 24 25 26 27 28

我在你的代码中看到的第一个问题是：为什么你在启动它之后使用了一段时间和一个休息时间？您似乎只需要 if 语句，而不是而。

其次，您对日历的任何一行都使用相同的逻辑，这意味着：它们从星期一开始，到星期日结束。

您应该为第一行更改内部 for 循环的起点，具体取决于它开始的日期。

一个简单的字典可以保存与一周中每一天相关联的数字，并且在第一周您将其用作for的起点，而不是 1 。

您的代码仅适用于本月的第一天的周一和周日。要使它适用于任何第一天，您应该更改打印空间的方式，根据第一天更改它。

包含更改的代码：

月=＆＃39; 11月＆＃39; day =＆＃39; Sunday＆＃39; x = 30 n = 1

days = { 'Mo': 1, 'Tu': 2, 'We': 3, 'Th': 4, 'Fr': 5, 'Sa': 6, 'Su': 7 }
print("   "*(days[day[:2]]-1), end='') # print 3 spaces for each day that isn't the first day of the month
start = days[day[:2]] # Set the start of the inner loop to the first day of the month
for i in range (1, 7):
    for j in range (start, 8):
        start = 1
        if n < x+1:
           print('%2s' % n, end=' ')
           n = n + 1
    print()

使用月和日打印月份
