I want to understand what good practice is in terms of writing methods within a class that relate to one another.
When I run my code:
import pandas as pd
pd.options.mode.chained_assignment = None
class MyData:
def __init__(self, file_path):
self.file_path = file_path
def prepper_fun(self):
'''Reads in an excel sheet, gets rid of missing values and sets datatype to numerical'''
df = pd.read_excel(self.file_path)
df = df.dropna()
df = df.apply(pd.to_numeric)
self.df = df
return(df)
def quality_fun(self):
'''Checks if any value in any column is more than 10. If it is, the value is replaced with
a warning 'check the original data value'.'''
for col in self.df.columns:
for row in self.df.index:
if self.df > 10:
self.df = str('check original data value')
return(self.df)

def quad(x, a, b, c):
return a*x**2 + b*x + c
As you may notice it contains several parameters (viz. a, b, c) apart from the variable x. Now if I were to put this in a file and simply import it, the end user would have to always call the function with the parameters in addition to the variable. Because of this I was thinking of creating a class such as this:
class quad:
def __init__(self, a, b, c):
self.a = a
self.b = b
self.c = c
def eq(x):
return self.a*x**2 + self.b*x + self.c
Thus allowing the end user to use it as:
q = quad(p, q, r)
eq = q.eq
Is this the right way of doing things? I am terribly sorry about the title of the question, as I... less
