python - 如何在 Python 中创建表格

Question

我之前发布过这个，但我重新发布它并提供更详细的信息。

这是我的任务:

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():

正如我在第一篇文章中所说，除了设置该表之外，我对任何事情都没有真正的问题。我真的很困惑!

我问了我的导师(顺便说一句，这是一门在线类(class))，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。 "

现在我只是想知道从哪里开始。

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
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 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')
    elif 80 <= score <= 89:
        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)
print ("%s:\t\t\t%f\t\t%s") % ('name2', 'score2', determine_grade)
print ("%s:\t\t\t%f\t\t%s") % ('name3', 'score3', determine_grade)
print ("%s:\t\t\t%f\t\t%s") % ('name4', 'score4', determine_grade)
print ("%s:\t\t\t%f\t\t%s") % ('name5', 'score5', determine_grade)
print ("---------------------------------------------------------------")

但是当我运行它时:

编辑#2:这是我目前的代码:

# 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 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 60 <= score <= 69:
        print ('D')
    elif  70 <= score <= 79:
        print ('C')
    elif 80 <= score <= 89:
        print ('B')
    elif 90 <= score <= 100:
        print ('A')



# 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():
   print ("Name\t\t\tnumeric grade\t\tlettergrade")
print ("---------------------------------------------------------------")
print ("%s:\t\t\t%f\t\t%s" % ('name1', 93, 'A'))
print ("%s:\t\t\t%f\t\t%s" % ('name2', 89, 'B'))
print ("%s:\t\t\t%f\t\t%s" % ('name3', 76, 'C'))
print ("%s:\t\t\t%f\t\t%s" % ('name4', 58, 'F'))
print ("%s:\t\t\t%f\t\t%s" % ('name5', 98, 'A'))
print ("---------------------------------------------------------------")
print (calculate_average)

这是我运行它时发生的情况:

现在，我主要有两个问题:

1) 如何让输入语句在表格显示之前执行并输入数据？

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)。

希望是最终的编辑:我真的很接近解决方案，但还需要其他一些帮助。

这是我的代码:

# Define a function that prompts the user to input names and test scores

score = input('Enter score 1:')
name1 = input('Enter name 1:')
score = input('Enter score 2:')
name2 = input('Enter name 2:')
score = input('Enter score 3:')
name3 = input('Enter name 3:')
score = input('Enter score 4:')
name4 = input('Enter name 4:')
score = 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')
    elif 80 <= score <= 89:
        print ('B')
    elif 90 <= score <= 100:
        print ('A')

determine_grade(score)


# Define a function that caculates average test scores
def calculate_average(score):
    total = score + score + score + score + score
    average = total / 5
    print(average)

calculate_average(score)

# 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():
   print ("Name\t\t\tnumeric grade\t\tlettergrade")
print ("---------------------------------------------------------------")
print ("%s:\t\t\t%f\t\t%s" % ('name1', 'score', determine_grade('score')))
print ("%s:\t\t\t%f\t\t%s" % ('name2', 'score', determine_grade('score')))
print ("%s:\t\t\t%f\t\t%s" % ('name3', 'score', determine_grade('score')))
print ("%s:\t\t\t%f\t\t%s" % ('name4', 'score', determine_grade('score')))
print ("%s:\t\t\t%f\t\t%s" % ('name5', 'score', determine_grade('score')))
print ("---------------------------------------------------------------")
calculate_average(score)

这就是我按 F5 时发生的情况:

伙计们，我差不多完成了，只需要格式化方面的帮助:我创建了另一个文件，这样我就可以重新组织我的代码，所以这就是为什么没有评论。这是我的:

score1 = float(input('Enter score 1:'))
name1 = input('Enter name 1:')
score2 = float(input('Enter score 2:'))
name2 = input('Enter name 2:')
score3 = float(input('Enter score 3:'))
name3 = input('Enter name 3:')
score4 = float(input('Enter score 4:'))
name4 = input('Enter name 4:')
score5 = float(input('Enter score 5:'))
name5 = input('Enter name 5:')

当我运行它时:

Answer 1

您应该为打印语句寻找 str.format() 和 end=''

举个例子

for x in range(10):
    print("{:<10}".format("{:0.1f}".format(x)), end='')

浮点值四舍五入到小数点后一位的第一部分是

"{:0.1f}".format(x)

0表示没有左填充，后面的.1f表示四舍五入到小数点后一位。接下来是重头戏

"{:<10}".format(...)

这将打印最小长度为 10 个字符的字符串。因此，如果您有一个字符串，例如 Hello，它会被打印为 Hello_____(_ 代表空格) 10 可以更改为一个值由您选择。

最后是 end=''。默认情况下，end 参数是 \n，这是在每次打印后创建新行的原因，但通过更改它，您可以从多个打印语句中形成行。只需正常打印或设置 end='\n' 当你想结束该行。

还有一点需要注意。当检查一个值是否在两个整数之间时，你可以使用它而不是检查它两次(你也需要和 and 运算符而不是 or )

elif 60 <= score <= 69:
