Can someone help me figure out what this error is telling me? I don't understand why this csv won't load.
Code:
import pandas as pd
import numpy as np
energy = pd.read_csv('Energy Indicators.csv')
GDP = pd.read_csv('world_bank_new.csv')
ScimEn = pd.read_csv('scimagojr-3.csv')
Error:
UnicodeDecodeError Traceback (most recent call last)

5 GDP = pd.read_csv('world_bank_new.csv')
----> 6 ScimEn = pd.read_csv('scimagojr-3.csv')

The read_csv function takes an encoding option. You're going to need to tell Pandas what the file encoding is. Try encoding = "ISO-8859-1".

I have tried all the answers that has been posted on the forum but I keep getting thrown this error
How do I correct this error?

I have tried the responses posted here No module named 'sklearn.neighbors.base' still existed after all the suggestions what I can take
but I get the same error
It seems to be correct,
try updating your packages,
Code Output:
I recently started coding in Python. I'm importing a csv file containing around 848 unique locations across India, and would like to use the geopy module to add in latitude and longitude for each location. After importing the data, I used this code:
from geopy.geocoders import Nominatim
import pandas as pd
df = pd.read_csv("../project/LocationIndia.csv")
lat = []
long = []
for location in df["Location"]:
# Initialize Nominatim API
address = location + ', India'
geolocator = Nominatim(user_agent="MyApp")
location = geolocator.geocode(address)
lat.append(location.latitude)
long.append(location.longitude)
df['latitude']=latitude
df['longitude']=longitude
df
Output:
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)

----> 9 lat.append(location.latitude)

11 df['latitude']=latitude
AttributeError: 'NoneType' object has no attribute 'latitude'
Not sure why this is happening. If anyone can help me out, would be great, thanks!
This is the table btw:
Location
0 Kharghar
1 Sector-13 Kharghar
2 Sector 18 Kharghar
3 Sector 20 Kharghar
4 Sector 15 Kharghar
... ...
843 BTM Layout
844 Kuvempu Layout on Hennur Main Road
845 Marathahalli
846 Rajajinagar
847 RMV
I was expecting values to be inputted as columns in the dataframe.
geolocator.geocode() returns None, if no results are found. Try error handling like:
if location is not None:

I'm trying to calculate the daily returns of stock in percentage format from a CSV file by defining a function.
Here's my code:
def daily_ret(ticker):
return f"{df[ticker].pct_change()*100:.2f}%"
When I call the function, I get this error:
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-40-7122588f1289> in <module>()
----> 1 daily_ret('AAPL')

1 def daily_ret(ticker):
----> 2 return f"{df[ticker].pct_change()*100:.2f}%"
TypeError: unsupported format string passed to Series.__format__
Where am I going wrong?
f-strings can't be used to format iterables like that, even Series:
Use map or apply instead:
def daily_ret(ticker):
return (df[ticker].pct_change() * 100).map("{:.2f}%".format)
def daily_ret(ticker):
return (df[ticker].pct_change() * 100).apply("{:.2f}%".format)
import numpy as np
import pandas as pd
df = pd.DataFrame({'A': np.arange(1, 6)})
print(daily_ret('A'))
0 nan%
1 100.00%
2 50.00%

I have a csv contains about 600K observations, and I'm importing it using fread
DT = dt.fread('C:\\Users\\myamulla\\Desktop\\proyectos_de_py\\7726_analysis\\datasets\\7726export_Jan_23.csv')
It is throwing out an error as -
--------------------------------------------------------------------------

IOError: Too few fields on line 432815: expected 14 but found only 4 (with sep=','). Set fill=True to ignore this error. <<19731764,2021-01-23 23:30:15,2021-01-23 23:42:20,"Vote for David Borrero, your Republican in HD 105. Potestad betrayed Prez Trump. Borrero is for our values & POTUS Trump.>>
As suggested here, i passed the argument fill=True in fread statement.
DT = dt.fread('C:\\Users\\myamulla\\Desktop\\proyectos_de_py\\7726_analysis\\datasets\\7726export_Jan_23.csv',fill=True)
It executes, but DT will be created EMPTY.
How to get it resolved ?

The GraphLab forum http://forum.graphlab.com/discussion/84/importerror-undefined-symbol-pyunicodeucs4-decodeutf8 suggests that this is due to Enthought Python being compiled with 2-byte-wide unicode chars. Is there a way to get Enthought to use 4-byte chars since I can't recompile?
