I'm trying to make a histogram with data from a .CSV file. I put together the code below and I'm getting an ''int' object is not iterable' error when I run it, any ideas?
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
file = "...sp histo.csv"
data = pd.read_csv(file)
year_2016 = np.array(data['2016'])
year_2017 = list(np.array(data['2017']))
small_ret = min(min(year_2016),min(year_2017))
large_ret = max(max(year_2016),max(year_2017))
bins = np.arange(small_ret, large_ret, 0.1)
plt.hist(year_2017,bins=bins, range = 20)
plt.show()
