Hi$,$ This Question is creating so much problem for me$.$ I was able to get the result but when loading to Code Grade, I get an error message $-$ "IndexError: list index out of range $"$

I spend so much time trying to solve this problem using python and sys$.$argv but was not successful. This is the code I used

import sys

import pandas as pd

import statsmodels.api as sm

def main$()$:

if len$($sys$.$argv$)!=2$:

print$("$Usage: python german.py $")$

#sys$.$exit$(1)$

return

file$\_$path $=$ sys$.$argv$[1]$

try:

data $=$ pd$.$read$\_$csv$($file$\_$path$)$

except FileNotFoundError:

print$("$File not found."$)$

#sys$.$exit$(1)$

return

data.rename$($columns$=\{\text{'}$Credit amount': 'Credit$\_$amount'$\},$ inplace$=$True$)$

X $=$ sm$.$add$\_$constant$($data$[[\text{'}$Age$\text{'},$ 'Duration'$]])$

y $=$ data$[\text{'}$Credit$\_$amount'$]$

model $=$ sm$.$OLS$($y$,$ X$).$fit$()$

#print$("$Parameters:$")$

print$($model$.$params.round$(2))$

#print$("$nR$-$squared:"$)$

print$($model$.$rsquared.round$(2))$

if $\_\_$name$\_\_=="\_\_$main$\_\_"$:

main$()$german$.$py

Use the german$\_$credit$\_$data.csv file to complete the following assignment.

Create a file,

german.py$,$ that loads the $.$csv file and runs a regression predicting

credit amount from age and duration, in that order. Add a constant using

sm$.$add$\_$constant$($data$).$

You will need to rename the column 'Credit amount' to 'Credit$\_$amount'.

Then, print the parameters and R$-$squared to $2$ decimals using
