How To Create A Table in Python
提问by Baroness Sledjoys
I've posted this before, but I'm reposting it with more detailed information.
我以前发布过这个，但我重新发布了更详细的信息。
This is my assignment:
这是我的任务：
And, so far, this is my code:
而且，到目前为止，这是我的代码：
# Define a function that caculates average test scores
def calculate_average(score1, score2, score3, score4, score5):
total = score1 + score2 + score3 + score4 + score5
average = total % 5
print(average)
# Define a function that determines a letter grade
# Based on the given score
def determine_grade(score):
if score < 60:
print 'F'
elif score => 60 or score <= 69:
print 'D'
elif score => 70 or score <= 79:
print 'C'
elif score => 80 or score <= 89:
print 'B'
elif score => 90 or score <= 100:
print 'A'
# Define a function that prompts the user to input names and test scores
def input_data():
score1 = input('Enter score 1:')
name1 = input('Enter name 1:')
score2 = input('Enter score 2:')
name2 = input('Enter name 2:')
score3 = input('Enter score 3:')
name3 = input('Enter name 3:')
score4 = input('Enter score 4:')
name4 = input('Enter name 4:')
score5 = input('Enter score 5:')
name5 = input('Enter name 5:')
# Define a function that displays a letter grade for each score
# followed by the student's name and the average test score
def display_menu():
As I said in the first post, I don't have a real problem with anything except setting up that table. I'm really confused!
正如我在第一篇文章中所说，除了设置那张桌子之外，我对任何事情都没有真正的问题。我真的很困惑！
I asked my instructor (this is an online course, BTW), and he said: "Its just using the print operator, like you have done in previous modules, your printing text , variables and the return value of a function."
我问过我的导师（这是一个在线课程，顺便说一句），他说：“它只是使用打印运算符，就像你在之前的模块中所做的那样，打印文本、变量和函数的返回值。”
Now I'm just wondering where to start.
现在我只是想知道从哪里开始。
EDIT:I've updated my code this:
编辑：我已经更新了我的代码：
# Define a function that prompts the user to input names and test scores

score4 = input('Enter score 4:')
name4 = input('Enter name 4:')
score5 = input('Enter score 5:')
name5 = input('Enter name 5:')
# Define a function that determines a letter grade
# Based on the given score
def determine_grade(score):
if score < 60:
print ('F')
elif 60 <= score <= 69:
print ('D')
elif 70 <= score <= 79:
print ('C')

print ('B')
elif 90 <= score <= 100:
print ('A')
# Define a function that caculates average test scores
def calculate_average(score1, score2, score3, score4, score5):
total = score1 + score2 + score3 + score4 + score5
average = total / 5
print(average)
# Define a function that displays a letter grade for each score
# followed by the student's name and the average test score
def display_menu():
for x in range(10):
print("{:<10}".format("{:0.1f}".format(x)), end='')
print ("Name\t\t\tnumeric grade\t\tletter grade")
print ("---------------------------------------------------------------")
print ("%s:\t\t\t%f\t\t%s") % ('name1', 'score1', determine_grade)

这就是我运行它时发生的情况：
Now, I have mainly two problems:
现在，我主要有两个问题：
1) How do I get the input statements to execute and enter the data BEFORE the table is displayed?
1) 如何在显示表之前获取要执行的输入语句并输入数据？
2) How do I convert the numbers displayed so that they are in the '.2f' format? (I've already tried a few ways and none of them worked).
2) 如何将显示的数字转换为“.2f”格式？（我已经尝试了几种方法，但都没有奏效）。
HOPEFULLY THE FINAL EDIT:I'm getting really close to the solution, but need help with a few more things.

You should be looking towards str.format()and end=''for your print statement
您应该寻找str.format()并end=''寻找您的印刷声明
Here's a little example
这是一个小例子
for x in range(10):
print("{:<10}".format("{:0.1f}".format(x)), end='')
The first part for the rounding to 1 decimal place for your float values is
将浮点值舍入到小数点后一位的第一部分是
"{:0.1f}".format(x)
The 0is for no left padding, the following .1fis for rounding to 1 decimal place. Next is the main part
的0是对于没有左填充，以下.1f是用于四舍五入至1个小数位。接下来是主要部分
"{:<10}".format(...)
This will print with a minimum string length of 10 characters. So if you have a string such as Helloit is printed as Hello_____( _ to represent empty spaces) The 10can be changed to a value of your choosing.
这将打印最少 10 个字符的字符串长度。因此，如果您有一个字符串，例如Hello它被打印为Hello_____（ _ 表示空格），则10可以将其更改为您选择的值。
Finally the end=''. By default the endparameter is \nwhich is what creates the new line after each print, but by changing it you can form lines from multiple print statements. Just print normally or set end='\n'when you want to end the line.
最后将end=''. 默认情况下，end参数是\nwhich 在每次打印后创建新行，但通过更改它，您可以从多个打印语句中形成行。只需正常打印或end='\n'在要结束该行时进行设置。
Little something to note as well. When checking if a value is between two integers you can use this instead of checking it twice (also you would need and andoperator instead of or)
还有一点要注意。当检查一个值是否在两个整数之间时，您可以使用 this 而不是检查两次（您也需要 andand运算符而不是or）
elif 60 <= score <= 69:

You could do something like this:
你可以这样做：
def display_menu():
print "Name\t\t\tnumeric grade\t\tlettergrade"
print "---------------------------------------------------------------"
print "%s:\t\t\t%f\t\t%s" % ('name1', 50, 'F')
print "%s:\t\t\t%f\t\t%s" % ('name2', 50, 'F')
print "%s:\t\t\t%f\t\t%s" % ('name3', 23, 'F')
print "%s:\t\t\t%f\t\t%s" % ('name4', 44, 'F')
print "%s:\t\t\t%f\t\t%s" % ('name5', 48, 'F')
print "---------------------------------------------------------------"
display_menu()
显示菜单（）
I used \tto give tabs in between.
我曾经\t在两者之间给出标签。

Well, I just got the solution back, and I did a real butchering on the code. But, I will post this so no one will have to suffer like I did:
好吧，我刚刚得到了解决方案，并且我对代码进行了真正的屠杀。但是，我会发布这篇文章，所以没有人会像我一样受苦：

name4 = input('Enter name 4:')
score5 = float(input('Enter score 5:'))

average = calculate_average(score1, score2, score3, score4, score5)
#Display grade and average information in tabular form
