问题:我需要将金额转换为印度货币格式

Problem: I need to convert an amount to Indian currency format

我的代码:我有以下 Python 实现:

import decimal
def currencyInIndiaFormat(n):
  d = decimal.Decimal(str(n))
  if d.as_tuple().exponent < -2:
    s = str(n)
  else:
    s = '{0:.2f}'.format(n)
  l = len(s)
  i = l-1;
  res = ''
  flag = 0
  k = 0
  while i>=0:
    if flag==0:
      res = res + s[i]
      if s[i]=='.':
        flag = 1
    elif flag==1:
      k = k + 1
      res = res + s[i]
      if k==3 and i-1>=0:
        res = res + ','
        flag = 2
        k = 0
    else:
      k = k + 1
      res = res + s[i]
      if k==2 and i-1>=0:
        res = res + ','
        flag = 2
        k = 0
    i = i - 1

  return res[::-1]

def main():
  n = 100.52
  print "INR " + currencyInIndiaFormat(n)  # INR 100.52
  n = 1000.108
  print "INR " + currencyInIndiaFormat(n)  # INR 1,000.108
  n = 1200000
  print "INR " + currencyInIndiaFormat(n)  # INR 12,00,000.00

main()

我的问题:有没有办法让我的 currencyInIndiaFormat 函数更短、更简洁、更干净?/有没有更好的方法来编写我的 currencyInIndiaFormat 函数?

My Question: Is there a way to make my currencyInIndiaFormat function shorter, more concise and clean ? / Is there a better way to write my currencyInIndiaFormat function ?

注意:我的问题主要是基于上述问题的Python实现.这不是之前关于将货币转换为印度格式的问题的重复.

Note: My question is mainly based on Python implementation of the above stated problem. It is not a duplicate of previously asked questions regarding conversion of currency to Indian format.

印度货币格式:

例如，这里的数字表示为:

For example, numbers here are represented as:

1
10
100
1,000
10,000
1,00,000
10,00,000
1,00,00,000
10,00,00,000

参考印度编号系统

解决方案

工作量太大.

>>> import locale
>>> locale.setlocale(locale.LC_MONETARY, 'en_IN')
'en_IN'
>>> print(locale.currency(100.52, grouping=True))
₹ 100.52
>>> print(locale.currency(1000.108, grouping=True))
₹ 1,000.11
>>> print(locale.currency(1200000, grouping=True))
₹ 12,00,000.00
