how to pass a dataframe into string and call function from it?

Question

i'm passing a function who needs a dataframe to execute it, inside a variable string, and using the eval metric i'm trying to execute the function. But the code isn't working because the dataframe becames a string and it fails to understend it.

What i'm doing is:

def function(dataframe, number1, number2):
    print(dataframe) #I need this print(dataframe) to print the dtaframe in the correct dataframe format
    print(number1+number2)

dataframe = pandas.DataFrame()
number1 = 1
number2 = 1
a = f'function{dataframe, number1, number2}'
eval(a)

But this do'nt work

this calls the function automatic, i need to call it just when i use eval — yyz_vanvlet, Apr 02 '20 at 17:03

You can just call the function and it will work:

from IPython.display import display, HTML
import pandas

def function(dataframe, number1, number2):
    display(HTML(dataframe.to_html()))
    print(number1+number2)

dataframe = pandas.DataFrame()
number1 = 1
number2 = 1
a = f'function(dataframe, number1, number2)'
eval(a)

If you want to display the datafram in good formatting I suggest reading here: Show DataFrame as table in iPython Notebook

i need to use eval, because i need to put many functions in a list and without it, when i declare the list, it calls the function without me wanting it – yyz_vanvlet Apr 02 '20 at 17:07
Just edited, see if that's what you want @yyz_vanvlet – Bruno Mello Apr 02 '20 at 17:10
