支票金额大小写转换器

以下是一个简单的支票金额大小写转换器的Python代码示例。这个转换器可以将数字金额转换为标准的支票金额格式，包括数字和对应的大小写文字。

```python

def number_to_english(num):

units = ['', 'Thousand', 'Million', 'Billion', 'Trillion']

under_20 = ['Zero', 'One', 'Two', 'Three', 'Four', 'Five', 'Six', 'Seven', 'Eight', 'Nine', 'Ten',

'Eleven', 'Twelve', 'Thirteen', 'Fourteen', 'Fifteen', 'Sixteen', 'Seventeen', 'Eighteen', 'Nineteen']

tens = ['', '', 'Twenty', 'Thirty', 'Forty', 'Fifty', 'Sixty', 'Seventy', 'Eighty', 'Ninety']

def convert_thousand(num):

if num == 0:

return ''

elif num < 1000:

return convert_hundred(num)

else:

return convert_hundred(num // 1000) + ' ' + units[3] + (convert_thousand(num % 1000) if num % 1000 else '')

def convert_hundred(num):

if num == 0:

return ''

elif num < 100:

return under_20[num] + (' ' + units[1] if num < 20 else '')

else:

return under_20[num // 100] + ' Hundred' + (' ' + convert_tens_and_units(num % 100) if num % 100 else '')

def convert_tens_and_units(num):

if num < 20:

return under_20[num]

else:

return tens[num // 10] + (' ' + under_20[num % 10] if num % 10 else '')

return convert_thousand(num)

def convert_amount_to_english(amount):

if amount < 0:

return 'Invalid amount'

if amount == 0:

return 'Zero Dollars and 00/100'

dollars = int(amount)

cents = int((amount dollars) 100)

dollar_english = number_to_english(dollars)

if dollars == 1:

dollar_english += ' Dollar'

else:

dollar_english += ' Dollars'

if cents == 0:

return dollar_english + ' and 00/100'

else:

return dollar_english + ' and ' + str(cents) + '/100'

Example usage:

amount = 1234567.89

english_amount = convert_amount_to_english(amount)

print(english_amount)

```

这段代码定义了两个函数：`number_to_english`用于将数字转换为英文表示，`convert_amount_to_english`用于将金额转换为支票格式的大小写英文表示。你可以通过修改`amount`变量的值来测试不同的金额。
