Hi @Nikita_Mohanta,
Your kernel is stuck in a loop or may be some internel error. Try to restart your kernel or use a new notebook. If happens sometimes when there are a lot of codes in a single notebook.
I hope it helps.

sir please help me to solve this problem
- Define a function with the name
str_functhat takes one argument and returns the last character of the string passed to the function as a parameter.
Sample Input:
str_func('1234')
Sample Output:
'4'
- Define another function with the name
sum_str_functhat takes one argument and returns the sum of all digits in that number. The argument passed can bestror anint. You need to convert the integer to a string to calculate it’s length, and then use a loop to add each digit to calculate the sum of all digits.
Sample Input:
sum_str_func('1234')
Sample Output:

Hi Anju Peeter, would request you to comment below the assessment with a screenshot of your code and the error that you are getting. Also, please note that you need to write your code in the default notebook given on the right side of the split screen.
columnsToScale = ['temp','hum','windspeed']
scaler = StandardScaler()
train_set[columnsToScale] = scaler.fit_transform(train_set[columnsToScale])
test_set[columnsToScale] = scaler.transform(test_set[columnsToScale])
train_set[columnsToScale].describe()

Hi Sandee,
It doesn’t work even if is without the ls. It seems like the file doesn’t exist. Do you downloaded the file ?? mind sharing ?
Submit button is not working
The following code worked for me:
import pandas as pd
df = pd.read_csv('/cxldata/datasets/project/ny_stock_prediction/prices-split-adjusted.csv')

Hi,
Could you share the details?
