python - Get content of a string variable using getattr -


i know how retrieve content of string variable can use value argument name in function. here code:

import pandas import jinja2  odatelist = ['2017-03-22','2017-03-23','2017-03-24'] odata = pandas.dataframe() odata['date'] = odatelist mytemplate = 'today {{ date }}' otemplate = jinja2.template(mytemplate)  orow in odata.index:     ocolumn in odata.columns:         mytemplateupdated = otemplate.render(date=odata.loc[orow, ocolumn])         print(mytemplateupdated)

it works , returns:

today 2017-03-22 today 2017-03-23 today 2017-03-24

i dynamically retrieve argument name date= dataframe column name ocolumn (which 'date'). thought using getattr(ocolumn, 'something') did not figure out how so.

i have tried str(ocolumn) , returns error: syntaxerror: keyword can't expression

thank you

if want dynamically set argument name being sent function, you'll need use kwargs.

render(**{argument_name: argument_value}

so in case, assuming ocolumn contains string wish argument, this;

render(**{ocolumn: odata.loc[orow, ocolumn]})

let me know if have misunderstood intent.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
