如何在 Python 中实现 Act / Act 约定？

Question

If there are two given dates(eg, from Oct 12, 2016 to Nov 21, 2019). Based on the Act/Act Convention, how can I calculate the amount of days by the "While" or "IF" loop?

Answer 1

You can use datetime module, ie:

from datetime import datetime

df = "%b %d, %Y"
start = datetime.strptime('Oct 12, 2016', df)
end = datetime.strptime('Nov 21, 2019', df)
diff = end - start
print (diff.days)
# 1135
