How to get currency in Indian format using python?

I have following amounts:

1000
1234
123400
1900000

How can i convert these to:

1 Thousand
1.2 Thousand
1.2 Lakhs
19 Lakhs

I tried a function from this link Convert an amount to Indian Notation in Python.

def format_indian(t):
  dic = {
      4:'Thousand',
      5:'Lakh',
      6:'Lakh',
      7:'Crore',
      8:'Crore',
      9:'Arab'
  }
  y = 10
  len_of_number = len(str(t))
  save = t
  z=y
  while(t!=0):
    t=int(t/y)
    z*=10

  zeros = len(str(z)) - 3
  if zeros>3:
      if zeros%2!=0:
          string = str(save)+": "+str(save/(z/100))[0:4]+" "+dic[zeros]
      else:   
        string = str(save)+": "+str(save/(z/1000))[0:4]+" "+dic[zeros]
        return string
  return str(save)+": "+str(save)

But this is giving me:

format_indian(100001)
>>> '100001: 100001'

How can I make that to:1 lakhs, the above solution only works for 10's of every category. For example: 10 Thousand, 10 Lakhs, 10 crore

You can use num2words package of Python. It converts numbers to words.

https://pypi.org/project/num2words/

This code will convert number to words in Indian format.

from num2words import num2words

print(num2words(100000, lang='en_IN'))

Output:

one lakh

Just like Ram said, you can use the package: https://pypi.org/project/num2words/ and you can use a dictionary and try except

num2words = {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', 0: 'Zero'}

>>> def n2w(n):
        try:
            print num2words[n]
        except KeyError:
            try:
                print num2words[n-n%10] + num2words[n%10].lower()
            except KeyError:
                print 'Number out of range'

>>> n2w(0)
Zero
>>> n2w(13)
Thirteen        
>>> n2w(91)
Ninetyone
>>> n2w(21)
Twentyone
>>> n2w(33)
Thirtythree

!pip install inflect

Not in the Indian Currency but you can get it in strings

import inflect
p = inflect.engine()

so p.number_to_words(1900000)

will give you

one million, nine hundred thousand

but if you only need in Indian Currency then you can modify 3rd answer of this SO thread

Just building up on your existing code, you can try something like this if you want the 1st part to still show numbers, else @Ram answer should work fine.

import math
def format_indian(t):
    num_count = {
        3 : 'Hundred',
        4 : 'Thousand',
        5 : 'Thousand',
        6 : 'Lakh',
        7 : 'Lakh',
        8 : 'Crore',
        9 : 'Crore',
        10: 'Arab'
    }
    num_len = len(str(t))
    power = num_len - 1 if (num_len % 2 == 0 or num_len == 3) else num_len - 2
    dig = t / math.pow(10, power)
    print("{} {}".format(round(dig,1), num_count[num_len]))

You can adjust the round-off value based on the precision you want.
