I am trying to make a class I can use to save a dataframe, two strings and two floats.
I cant seem to get it to work.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46

import numpy as np import os import matplotlib import matplotlib.pyplot as plt matplotlib.use('wxAgg')  # matplotlib backend needed to work with wxPython GUI import time from datetime import datetime import pandas as pd       selected_dir = r"C:\Users\cstreb\Desktop\Data Visualization" path = r"C:\Users\cstreb\Desktop\Data Visualization\Test1.xlsm" df = pd.read_excel (path, sheet_name='DefocusData', names = ["Description","Defocus","Tan","Sag"]) Title = os.path.basename(path) print (Title) Time = os.path.getmtime(path) local_time = time.ctime(Time) print("Last modification time(Local time):", local_time)   FieldAngles = ((df.loc[df['Description'] == 'THF Field Angle, Roll Angle']).iloc[:,1]) DefocusPlanes = ((df.loc[df['Description'] == 'Number of THF Planes']).iloc[:,1]) DefocusFrequency = ((df.loc[df['Description'] == 'Defocus Frequency']).iloc[:,1]) print (DefocusFrequency) for x in DefocusPlanes.index:     print (x)     print (df.iloc[(x+3):(x+3+DefocusPlanes[x]), 1:4])       class geeks:      def __init__(self):          self.DFAngSagTang = pd.dataframe         self.FileName = ""         self.Date = ""         self.FieldAngle = -1         self.LP = -1     def AddDefocusPlane(DefocusPlane, FieldAngle, DefocusFrequency, Title, local_time):         self.DFAngSagTang = DefocusPlane         self.FileName = Title         self.Date = local_time         self.FieldAngle = FieldAngle         self.LP = DefocusFrequency   for x in DefocusPlanes.index:     FieldAngle = (FieldAngles[x-1])     DefocusPlane = (df.iloc[(x+2):(x+2+DefocusPlanes[x]), 1:4])     print (DefocusPlane)     SingleRunData.AddDefocusPlane(DefocusPlane, FieldAngle, DefocusFrequency, Title, local_time)     RunData.append(SingleRunData)

I get the following error -=-=-=-=-=-=-=-=-

Defocus Tan Sag
8 -50.8 9.2 10.1
9 -24.7 29.8 30.1
10 0.7 39.4 39.5

I get the following errors. Any help would be great , thank you. New Bee

You forgot self in your second class method. Should be:

1	def AddDefocusPlane(self, DefocusPlane, FieldAngle, DefocusFrequency, Title, local_time):

[chas777]

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

class OneDataSet:      def __init__(self, DFAngSagTang, FieldAngle, DefocusFrequency, Title, local_time):          self.DFAngSagTang = DFAngSagTang         self.FileName = Title         self.Date = local_time         self.FieldAngle = FieldAngle         self.LP = DefocusFrequency     def __call__(self, DFAngSagTang, FieldAngle, DefocusFrequency, Title, local_time):          self.DFAngSagTang = DFAngSagTang         self.FileName = Title         self.Date = local_time         self.FieldAngle = FieldAngle         self.LP = DefocusFrequency SingleRunData = OneDataSet RunData = [] for x in DefocusPlanes.index:     FieldAngle = (FieldAngles[x-1])     DefocusPlane = (df.iloc[(x+2):(x+2+DefocusPlanes[x]), 1:4])     SingleRunData(DefocusPlane, FieldAngle, DefocusFrequency, Title, local_time)     RunData.append(SingleRunData)

Now I am trying to get data out ! I write

1	len (RunData)

and get 3
I try

1	RunData[0]

and get __main__.OneDataSet
I try

1	RunData[0].DFAngSagTang

and it doesnt like me !

Last hertel thank you

[BrendanD]

One other mistake I missed. When you instantiate a class you must include parenthesis:

1	SingleRunData = OneDataSet()

[chas777]

Thanks for that but "SingleRunData = OneDataSet" seems to work

But I am not able to get data back out ! I am trying though

Yeahhhhhhh. Thank you for the help @BrendanD. You were correct after all. if I instantiate , I need all my parameters !!!

1 2 3 4 5 6 7 8 9 10

RunData = []   for x in DefocusPlanes.index:     FieldAngle = (FieldAngles[x-1])     DefocusPlane = (df.iloc[(x+2):(x+2+DefocusPlanes[x]), 1:4])     SingleRunData = OneDataSet(DefocusPlane, FieldAngle, DefocusFrequency, Title, local_time)     RunData.append(SingleRunData)   for onedata in RunData:     print (onedata.FieldAngle)

So I moved it to one line !

1	SingleRunData = OneDataSet(DefocusPlane, FieldAngle, DefocusFrequency, Title, local_time)

Now I am happy !!! thank you
