Counting of rows in Excel Spreadsheet - dakrantau - Sep-28-2020
Howdy! Am a newbie, appreciate any guidance shared.
Given an excel with data with rows of information with a Field called cities: Melbourne, Singapore, Kuala Lumpur, New York.
How do I code to generate a graph counting how many entries belong e.g. to Melbourne / Singapore / and all the other cities? Trying for a horizontal or vertical bar chart for display.
Big thanks!
import pandas as pd
import matplotlib
import matplotlib.pyplot as plt
import seaborn as sns
import numpy as np
df = pd.read_excel (r'C:\Users\Data20192020.xlsx')
plt.style.use('seaborn-dark')
plt.plot(df['Cities'].value_counts())
plt.show()

df.value_counts() The Docs
Pandas has an amazing number of functions and features. Worth spending some time with it. Pandas from the ground up is a youtube video from PyCon 2015. 2.5 hours so it is a time commitment, but IMHO worth it.
