Pandas Data frames and sorting values

Question

I am having a difficult time with writing this hw assignment, and am not sure where I messed up. I have tried several things, and believe my issue lies in the sort_values or maybe in the groupby command.

The issue is that I want to only display graph data from the year 2007. (using pandas and plotly in jupyternotebook for my class). I have the graph I want mostly but cannot get it to display the data correctly. It simply isn't filtering out the years, or taking data from specific dates as requested.

  import pandas as pd
  import plotly.express as px
  df = pd.read_csv('Data/Country_Data.csv')

  print(df.shape)
  df.head(2)
  df_Q1 = df.query("year == '2007'")

  print(df_Q1.shape)
  df_Q1.head()

This is where the issue begins, because it prints a table with only header information. As in it prints all the column names, but none of the data for them, and then later on it displays a graph of what I assume is the most recent death data rather than the year 2007 as specified.
