How do i create a series that I can create a bar chart from

Question

I have a list of names: ['joe','brian','stephen']

i would like to create a bar chart in jupyter with names as indexes and the bar showing the numbers of letters in each name. How do I create a series which I can call ".plot(kind='bar')" on and get a bar chart like described?

import numpy as np
import matplotlib.pyplot as plt

bars = ['joe','brian','stephen']
height = [len(m) for m in bars]
y_pos = np.arange(len(bars))
plt.bar(y_pos, height, color=(0.2, 0.4, 0.6, 0.6))
plt.xticks(y_pos, bars)
plt.show()

You can try this,

import matplotlib.pyplot as plt

x =  ['joe','brian','stephen']
y = [len(m) for m in x]

plt.bar(x, y)
plt.show()

You can create a dataframe using your list of names and then apply len function.

import pandas as pd
import matplotlib.pyplot as plt

df = pd.DataFrame({'names':['joe','brian','stephen']},dtype=str)
df['name_len'] = df['names'].apply(len)

df.plot(kind='bar',x='names')
plt.show()
