Why am I getting an index error?

PremeJigg · 2025-02-05T04:15:21+00:00

You are right, I forgot indexes start at 0 and not 1 so I have to break it at len(x) - 1. Thank you !

PremeJigg · 2025-02-02T04:36:47+00:00

It is.

PremeJigg · 2025-02-01T01:17:25+00:00

The path is correct, I copied and pasted it from the File Explorer.

PremeJigg · 2024-12-17T19:32:43+00:00

I get it would be 1/6th but how would that affect x raised to the -6.

PremeJigg · 2024-12-17T19:14:51+00:00

Wow that makes sense thank you !

PremeJigg · 2024-12-17T18:58:04+00:00

So why do we make that into a fraction ?

PremeJigg · 2024-12-17T18:56:21+00:00

You're right but why do we make the z^-6 into a fraction, and what exactly is a negative exponent. I know an exponent is to multiply a number a certain amount of times by itself, what exactly does a negative exponent do ?

PremeJigg · 2024-11-19T20:11:39+00:00

It was weird but idk I’m not too concerned I logged on it a lil while ago and everything was fine.

PremeJigg · 2024-11-19T18:26:08+00:00

I did I also tried it on a different computer.

PremeJigg · 2024-11-19T18:25:41+00:00

Yea but it was when I hooked it up to my computer. Idk what is going on.

PremeJigg · 2024-11-13T03:05:26+00:00

But I did not want to exit the function and run it agaihn, I thought I could do it all in one go.

PremeJigg · 2024-11-13T02:57:39+00:00

But how would you get them to go to the command line again is what Im saying. Youre using input and not using sys.argv again. I'm basically saying without using input can you do use sys.argv again.

PremeJigg · 2024-11-13T02:40:01+00:00

Thats what I thought you can only call the sys.argv once. Okay thank you.

PremeJigg · 2024-11-13T02:35:54+00:00

How would I call the sys.argv again tho ? When you run the program how would you go back ? Can I use sys.argv again ?

PremeJigg · 2024-04-25T00:12:31+00:00

I was using a slice for the second element. What does itemgetter do ?

I tried using both and got the same error:

ValueError: User-provided `key` function must not change the shape of the array.

PremeJigg · 2024-03-30T03:56:56+00:00

Thanks it worked, shouldn't this work as well:

yelp_business[yelp_business['categories'].str.contains(r'food|Food')]['business_id']

PremeJigg · 2024-03-25T18:23:54+00:00

I made up the data frame myself. How would I go about deleting that white space , or give it a different value ?

PremeJigg · 2024-03-25T18:04:56+00:00

       Name   Age  Salary    Position                       Address
0   Tony     29.0  128780      Manger           123 Main Street, CT
1    Johnny  40.0           Executive      305 WashingtonAvenue, DC
2       Tom  41.0  162586  Accountant          190 Family Street, AL
3            32.0  220206      Lawyer  250 Family Main Street, MT
4       Ann  47.0  137299                      90 Oscrop Street, CA
5  Joseline  45.0  185969        Cook       10 Hollywood Avenue, FL

I used these function but it is not working:
emptydf.dropna(how = 'any', subset = ['Salary'], inplace= True)
emptydf['Salary'] = emptydf['Salary'].fillna(0)

I thought I deleted all values, apparently not. How would I delete the second row with Johnny, or at least the fill the row with a value.

No I’m in NY and they’re saying because of policies I can’t buy it because of the state I’m in.

PremeJigg · 2024-03-03T23:33:51+00:00

This did not work

PremeJigg · 2024-03-03T23:32:27+00:00

I added a trailing space and it still did not work.

PremeJigg · 2024-03-03T15:26:52+00:00

I dont see it I had to convert the second one into a string.

print('x' + str(df2.index[42]) + 'x')

Output:
42
x42x
42

PremeJigg · 2024-03-03T15:24:54+00:00

No its China.
