关于 python 3 中格式化的问题

Question

对于我们的 python class，我们需要使格式与给出的示例完美匹配。 该示例如下所示：

   Average       Gallons       Cost Per   
    Speed          Used         Gallon    
    65.62         72.41          2.07     

我的 output 看起来像这样：

Average       Gallons       Cost Per      
Speed         Used          Gallon        
65.62         72.41          2.07          

我需要知道如何将我的 output 格式化为示例中给出的格式。 帮助将不胜感激。 这是我的代码：

driven = 1050
mpg = 14.5
money = input("How much money was spent: ")
hours = input("Hours driven: ")
average = driven / hours
num = driven / mpg
cpg = money / num
print("{:<14}{:<14}{:<14}".format("Average", "Gallons", "Cost Per"))
print("{:<14}{:<14}{:<14}".format("Speed", "Used", "Gallon"))
print("{:<14.2f}{:<14.2f} {:<14.2f}".format(average, num, cpg))

提前致谢！

Answer 1

使用^而不是<应该可以解决问题：

driven = 1050
mpg = 14.5
money = int(input("How much money was spent: "))
hours = int(input("Hours driven: "))
average = driven / hours
num = driven / mpg
cpg = money / num
print("{:^14}{:^14}{:^14}".format("Average", "Gallons", "Cost Per"))
print("{:^14}{:^14}{:^14}".format("Speed", "Used", "Gallon"))
print("{:^14.2f}{:^14.2f} {:^14.2f}".format(average, num, cpg))

Output：

   Average       Gallons       Cost Per    
    Speed          Used         Gallon     
    52.50         72.41          27.62
