Question

不使用库函数如何在Python中打印任意数量的单词？有一些答案是使用库函数，但我想要核心代码。

Like:
    12345 = "twelve thousand three hundred and forty five"
    97835200 ="Nine core seventy eight lakh thirty five thousand two hundred"
    230100 = "Two lakh thirty thousand one hundred"

Answer 1

此代码：

>>>def handel_upto_99(number):
predef={0:"zero",1:"one",2:"two",3:"three",4:"four",5:"five",6:"six",7:"seven",8:"eight",9:"nine",10:"ten",11:"eleven",12:"twelve",13:"thirteen",14:"fourteen",15:"fifteen",16:"sixteen",17:"seventeen",18:"eighteen",19:"nineteen",20:"twenty",30:"thirty",40:"forty",50:"fifty",60:"sixty",70:"seventy",80:"eighty",90:"ninety",100:"hundred",100000:"lakh",10000000:"crore",1000000:"million",1000000000:"billion"}
if number in predef.keys():
    return predef[number]
else:
    return predef[(number/10)*10]+' '+predef[number%10]

>>>def return_bigdigit(number,devideby):
predef={0:"zero",1:"one",2:"two",3:"three",4:"four",5:"five",6:"six",7:"seven",8:"eight",9:"nine",10:"ten",11:"eleven",12:"twelve",13:"thirteen",14:"fourteen",15:"fifteen",16:"sixteen",17:"seventeen",18:"eighteen",19:"nineteen",20:"twenty",30:"thirty",40:"forty",50:"fifty",60:"sixty",70:"seventy",80:"eighty",90:"ninety",100:"hundred",1000:"thousand",100000:"lakh",10000000:"crore",1000000:"million",1000000000:"billion"}
if devideby in predef.keys():
    return predef[number/devideby]+" "+predef[devideby]
else:
    devideby/=10
    return handel_upto_99(number/devideby)+" "+predef[devideby]

>>>def mainfunction(number):
dev={100:"hundred",1000:"thousand",100000:"lakh",10000000:"crore",1000000000:"billion"}
if number is 0:
    return "Zero"
if number<100:
    result=handel_upto_99(number)

else:
    result=""
    while number>=100:
        devideby=1
        length=len(str(number))
        for i in range(length-1):
            devideby*=10
        if number%devideby==0:
            if devideby in dev:
                return handel_upto_99(number/devideby)+" "+ dev[devideby]
            else:
                return handel_upto_99(number/(devideby/10))+" "+ dev[devideby/10]
        res=return_bigdigit(number,devideby)
        result=result+' '+res
        if devideby not in dev:
            number=number-((devideby/10)*(number/(devideby/10)))
        number=number-devideby*(number/devideby)

    if number <100:
        result = result + ' '+ handel_upto_99(number)
return result

逐个复制三个函数并粘贴到python shell中。之后就这样跑：

解答：

>>>mainfunction(12345)
' twelve thousand three hundred forty five'

>>>mainfunction(0)
'Zero'

>>>mainfunction(100)
'one hundred'

>>>mainfunction(40230534)
' four crore two lakh thirty thousand five hundred thirty four'

Answer 2

你可以使用python中提供的第三方库num2word

num2word.to_card(1e25)
'ten septillion, one billion, seventy-three million, seven hundred and forty-one


this will avoid your long code and you can directly use it.

下面是一个可以将数字转换为单词的函数。它使用标准英文名称作为数字，但如果需要，您可以根据您的特殊名称对其进行修改。此功能最多可处理10 ^ 60个数字。通过调用函数使用它：int2word（n）其中n是数字

def int2word(n):
"""
convert an integer number n into a string of english words
"""
# break the number into groups of 3 digits using slicing
# each group representing hundred, thousand, million, billion, ...
n3 = []
r1 = ""
# create numeric string
ns = str(n)
for k in range(3, 33, 3):
    r = ns[-k:]
    q = len(ns) - k
    # break if end of ns has been reached
    if q < -2:
        break
    else:
        if  q >= 0:
            n3.append(int(r[:3]))
        elif q >= -1:
            n3.append(int(r[:2]))
        elif q >= -2:
            n3.append(int(r[:1]))
    r1 = r

#print n3  # test

# break each group of 3 digits into
# ones, tens/twenties, hundreds
# and form a string
nw = ""
for i, x in enumerate(n3):
    b1 = x % 10
    b2 = (x % 100)//10
    b3 = (x % 1000)//100
    #print b1, b2, b3  # test
    if x == 0:
        continue  # skip
    else:
        t = thousands[i]
    if b2 == 0:
        nw = ones[b1] + t + nw
    elif b2 == 1:
        nw = tens[b1] + t + nw
    elif b2 > 1:
        nw = twenties[b2] + ones[b1] + t + nw
    if b3 > 0:
        nw = ones[b3] + "hundred " + nw
return nw

'''Global'''

ones = ["", "one ","two ","three ","four ", "five ",
"six ","seven ","eight ","nine "]

tens = ["ten ","eleven ","twelve ","thirteen ", "fourteen ",
"fifteen ","sixteen ","seventeen ","eighteen ","nineteen "]

twenties = ["","","twenty ","thirty ","forty ",
"fifty ","sixty ","seventy ","eighty ","ninety "]

thousands = ["","thousand ","million ", "billion ", "trillion ",
"quadrillion ", "quintillion ", "sextillion ", "septillion ","octillion ",
"nonillion ", "decillion ", "undecillion ", "duodecillion ", "tredecillion ",
"quattuordecillion ", "sexdecillion ", "septendecillion ", "octodecillion ",
"novemdecillion ", "vigintillion "]
