Company vote 1

The file votes.txt contains the result of the vote held in a company. In each line there is the name of a shareholder (str), the number of shares she has (int), a Boolean (bool) that is True if she is a partner founder of the company and False otherwise, and another Boolean (bool) that is True if she approves the reform proposed and False otherwise. The file contains the following lines:

Dani 100 True True
Manel 5 False True
Maria 30 True True
Joan 20 True True
Nuria 150 False False

The first two lines correspond to the partner founder Dani, who has 100 shares and to the partner (not-founder) Manel, with 5 shares. Both have approved the reform. The rules to approve a reform in this company are the following:

• The partner founders have the right to veto. That is, if a partner founder votes against the reform, this is rejected.

• The vote of each shareholder is weighted with the number of shares she has. For instance, the vote of a shareholder has a value of 200 if she has 200 shares.

Write function company() that takes the name of a file (str) of the aforementioned characteristics, and returns a Boolean (bool) showing whether the reform has been approved or not. The reform will be approved if nobody with a right to veto has voted against it, and if more than half of the (weighted) votes are favourable. If the reform has been approved this function also returns the approval percentage (float); if it has not been approved due to a veto it must also return the string 'veto', and if it has not been approved due to the percentage, it must also return it (float).

In the example given, the reform would pass since no partner founder has voted against and there are 155 votes in favour and 150 against. Therefore the function will return True and a percentage of 50.82.
