Now, I have installed Python version 3.6.0 and I have struggled finding a suitable text for learning Python in this version. Even the online lecture series ask for versions 2.7 and 2.5 .
Now that I have got a book which, however, makes codes in version 2 and tries to make it as close as possible in version 3 (according to the author); the author recommends "downloading Anaconda for Windows" for installing Python.
So, my question is: What is this 'Anaconda'? I saw that it was some open data science platform. What does it mean? Is it some editor or something like Pycharm, IDLE or something?
Also, I downloaded my Python (the one that I am using right now) for Windows from Python.org and I didn't need to install any "open data science platform". So what is this happening?
Please explain in easy language. I don't have too much knowledge about these. less

This is the data set I'm working with:
SUMLEV REGION DIVISION STATE COUNTY STNAME CTYNAME
1 50 3 6 1 1 Alabama Autauga County
2 50 3 6 1 3 Alabama Baldwin County
3 50 3 6 1 5 Alabama Barbour County
4 50 3 6 1 7 Alabama Bibb County
What I am trying to do is to insert a column called TotalCounties that has the total count of counties by state as a last column. I've done similar things in SQL, but it doesn't seem to work quite the same in Python.
I have tried the code below, but the column ends up displaying as NaN instead of a number like I want it to.
counties_only_df = census_df[census_df
x = counties_only_df.groupby('STNAME').count()
counties_only_df = x

Please help me to fix the error or with an alternative approach to do candidate sampling.

But after converting PDF to Text file there appears few extra lines due to which I am not able to extract the data properly. Below is the text field yielded after the conversion. Can someone please tell me how to extract the Experience field from this file?
The below code works perfectly for those text files where there will be no blank lines.
with open('E:/cvparser/sampath.txt', 'r', encoding = 'utf-8') as f:
exp_summary_flag = False
exp_summary = ''
for line in f:
if line.startswith('EXPERIENCE'):
exp_summary_flag = True
elif exp_summary_flag:
exp_summary += line
if not line.strip(): break
print(exp_summary)
Here is the text file which I got after conversion using pdfminer.

fruits={
"apple":5,
"orange":7,
"mango":9
}
On reading the dictionary items, it should create 3 lists having same name as dictionary keys viz. apple, orange and mango and size of theses lists should be 5, 7 and 9 respectively. The elements of these lists should be given from the user through console.

ValueError: Error when checking target: expected dense_3 to have shape (3,) but got array with shape (1,)
I read multiple similar issues but none helped me so far. The error is on the last layer, where I've put 3 because this is the number of classes I'm trying right now.
The code is the following:

import cifar10 from keras.preprocessing.image
import ImageDataGenerator from keras.models
import Sequential
from keras.layers import Dense, Dropout, Activation, Flatten from keras.layers import Conv2D, MaxPooling2D
