The line chart i did is different from the answer. Why did it happen?
Screen Link: https://app.dataquest.io/m/142/line-charts/7/adding-data
My Code:
unrate12=unrate.loc[0:12,:]
plt.plot(unrate12['DATE'],unrate12['VALUE'])
plt.show()
You are doing great!
You just happen to plot the value more by 1. It should be unrate12=unrate.loc[0:11,:]
The answer shows unrated12=unrated12[0:12]
Now i get a little bit confused bewlow.
df[0:12]
df.loc[0:12]
Hey @candiceliu93
To answer your question -
df[0:12] is a shorthand convention of df.iloc[0:12]. This will slice the rows from our dataframe(unrated12) based on integer positions.
df.loc[0:12] is primarily label based, it can access a group of rows and columns by label(s) or a boolean array.
I believe your confusion is clear now. Just in case, if you want to refresh/ brush up your skills on df.loc & df.iloc, i suggest you to quickly go through our courses:

Got it now! After review the previous course, I think it help me to memories it firmly.
Thank you!!
