I'm using the Etherscan API to pull transactions logs for specific wallets, but I'm having a hard time trying to format the value correctly.

This is the url I'm working with Transaction Log

One of the transactions has a value of 206933340464 which in the etherscan site it looks like 0.00000020693334 if I use


I get 2.0693334. How can I format this value correctly?, or could it be that etherscan is providing wrong values?.

    Is that your exact code? When I do web3.fromWei(206933340464, 'ether'), I get "0.000000206933340464". – user19510 Dec 13 '17 at 16:33
  • Oh wow you're right. Using the Web3.js lib it's actually correct. I forgot to mention I'm using the Web3.py lib. Must be a bug then. Thank you!. – webjunkie Dec 13 '17 at 16:38

web3.py (at least the version I'm running) also gives the correct answer, but if you don't like the scientific notation, you'll have to use a format string:

>>> web3.fromWei(206933340464, 'ether')
>>> print('{:.14f}'.format(web3.fromWei(206933340464, 'ether')))
