Population Growth Over Years

This plot is nearly complete. You just need to adjust the ticks on the X-axis. We want a tick every 5 years. Define the ticks to complete the exercise.

import matplotlib.pyplot as plt

	82.06, 82.35, 82.67, 82.91, 83.02, 83.17
])
 
plt.plot(np.arange(2000,2021),population, linewidth=0.5, ls='--', marker='+')
 
# define X-ticks here...

 
plt.yticks(np.arange(81,84,0.5))
plt.grid(linestyle='--', linewidth=0.5)
plt.title('Population in Germany (2000-2020)')
plt.xlabel('Year')
plt.ylabel('Population (in millions)')
