伪代码 - zellers同余 - 蟒蛇

标签: python date pseudocode

我正在编程(python)中学习第一堂课。我的任务是编写伪代码,然后编写一个python程序,它将使用dd / mm / yyyy作为输入来计算星期几。我正在使用Zeller's congruence来计算星期几。这是我作为伪代码的第一次尝试 - 我希望得到一些反馈。我不确定我是否走在正确的轨道上。我的逻辑清楚吗?初学者能将它翻译成python吗?任何提示或帮助将不胜感激。

Program Calculate the Day
Purpose of the program: this program inputs a date and calculates the day of the week on which it occurred.
Date: 6/4/14

# Prompt a user to type his/her birthdate as three different values

print "In what month were you born?"
Input mm

print "on what day of the month?"
Input dd

print "In what year were you born?"
Input yyyy

# adjusts inputs to account for algorithm if birthdate occurs on Jan or Feb

if input mm = 1 or mm = 2:

mm = mm + 12 

and

yyyy = yyyy - 1

# stores inputs as variables for use in zellers congruence

store mm as m
store dd as q
store yyyy as y

# Calculate the day of the week and store it in a variable named dow

dow = ( ( q + ( (m + 1) * 26 // 10 )+ Y +( Y // 4 )+ 6 * (Y // 100 )+ (Y // 400 )) % 7 )

Output "you were born on a Day" dow

# Notice that there is no space between the word “Day” and the number; this helps it look like one of those “number for days” cultures
