pycse.utils#

These are some convenience utilities.

Float comparisons#

Floating point math is hard.

0.3 == 0.1 + 0.2

False

pycse.utils provides several floating point comparison operators:

  • feq a == b

  • flt a < b

  • fgt a > b

  • fle a <= b

  • fge a >= b

from pycse.utils import feq

feq(0.3, 0.1 + 0.2)

Temporarily ignore errors#

This context manager wraps code in a try/except/finally clause so you can ignore some errors.

Read a Google Sheet into a pandas Dataframe#

You can use a url to a Google Sheet that is publicly visible to read it into a pandas Dataframe.

from pycse.utils import read_gsheet
read_gsheet('https://docs.google.com/spreadsheets/d/1Qh4H5lHw_HOScAZqvII1VRPwCpPEJTHwkbo3a323azg/')
