Question

所以程序应该取一个数字，然后应该用文本打印这个数字。

print("Enter your number")
Number = int(input())


def number_to_text_ones(ones):
    if ones == 1:
        print("one")
    elif ones == 2:
        print("two")
    elif ones == 3:
        print("three")
    elif ones == 4:
        print("four")
    elif ones == 5:
        print("five")
    elif ones == 6:
        print("six")
    elif ones == 7:
        print("seven")
    elif ones == 8:
        print("eight")
    elif ones == 9:
        print("nine")


def number_to_text_tens(tens):
    if tens == 2:
        print("twenty ")
    elif tens == 3:
        print("thirty ")
    elif tens == 4:
        print("fourry ")
    elif tens == 5:
        print("fifty ")
    elif tens == 6:
        print("sixty ")
    elif tens == 7:
        print("seventy ")
    elif tens == 8:
        print("eighty ")
    elif tens == 9:
        print("ninety ")


def number_to_text_hundreds(hundreds):

    if hundreds == 1:
        print("one hundred")
    elif hundreds == 2:
        print("two hundreds")
    elif hundreds == 3:
        print("three hundreds")
    elif hundreds == 4:
        print("four hundreds")
    elif hundreds == 5:
        print("five hundreds")
    elif hundreds == 6:
        print("six hundreds")
    elif hundreds == 7:
        print("seven hundreds")
    elif hundreds == 8:
        print("eight hundreds")
    elif hundreds == 9:
        print("nine hundreds")


if Number == 0:
    print("zero")
elif Number == 10:
    print("ten")
elif Number == 11:
    print("eleven")
elif Number == 12:
    print("twelve")
elif Number == 13:
    print("thirteen")
elif Number == 14:
    print("fourteen")
elif Number == 15:
    print("fifteen")
elif Number == 16:
    print("sixteen")
elif Number == 17:
    print("seventeen")
elif Number == 18:
    print("eighteen")
elif Number == 19:
    print("nineteen")


if Number < 10:
    Result = Number % 10
    number_to_text_ones(Result)
elif (Number >= 20 and Number < 100):
    First = Number // 10
    Second = (Number - (First * 10)) % 10
    Result = First * 10 + Second
    number_to_text_tens(First)
    number_to_text_ones(Second)
elif (Number >= 100 and Number < 1000):
    First = Number // 100
    Second = (Number - (First * 100)) // 10
    Third = (Number - (First * 100) - (Second * 10)) % 10
    Result = First * 100 + Second * 10 + Third
    number_to_text_hundreds(First)
    number_to_text_tens(Second)
    number_to_text_ones(Third)

问题是当我输入时，例如，895我的输出将是：

eight hundreds

ninety 

five

我有几个问题：

如何让我的输出看起来更好？
有没有办法摆脱那些if语句并使用更高效的东西？像switch / case

Answer 1

以下是答案：

print函数有一个可选参数end，它指定将在您打印的字符串末尾写入的内容。默认为新行（'\n'）。你想用
```
print('something', end=' ')
```
比第一次构建一个名称为整数的字符串更好，最后只使用一次打印。

解决这个问题的好方法是使用字典，例如：

name = {1: "one hundred",
        2: "two hundreds",
        3: "three hundreds"}[hundreds]

Answer 2

你应该使用字典，因为它会减少代码行（if-else条件不再只是一个return语句就足够了）并且会让你的代码更好看，执行时间也会减少因为使用if-否则条件程序检查每个指定的条件，所以词典将帮助你很多

要将输出打印在一行中，这个更好

print(number_to_text_hundreds(First) + number_to_text_tens(Second) + number_to_text_ones(Third))

number_to_text_hundereds，number_to_text_tens和number_to_text_ones返回与传递给函数的值对应的值

Answer 3

我建议你使用字符串列表如下：

print("Enter your number")
Number = int(input())


units    = ['', 'one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine']
teens    = ["ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen"]
tens     = ['', '', "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety"]

h = Number // 100
t = (Number % 100) // 10
u = (Number % 10)

result = []

if h == 0:
    pass
elif h == 1:
    result.append('one hundred')
else:
    result.append(units[h] + ' hundreds')

if (t == 0):
    if (u != 0):
        result.append(units[u])
    elif (h == 0):
        result = ['zero']
elif (t == 1):
    result.append(teens[u])
else:
    result.append(tens[t])
    if (u != 0):
        result.append(units[u])

result = ' '.join(result)

print(result)
# input = 895 : result = 'eight hundreds ninety five'
# input = 507 : result = 'five hundreds seven'
# input = 120 : result = 'one hundred twenty'
# input = 071 : result = 'seventy one'
# input =  16 : result = 'sixteen'
# input =   0 : result = 'zero'

如何从一个线路中的2个不同功能获得2个输出？
