AttributeError: 'tuple' object has no attribute 'sum'-CodePudding

I'm trying to visualize some data using a pie chart in matplotlib.

But I'm getting this type of error and could not fix it.

I tried the following code:

import matplotlib.pyplot as plt
import numpy

labels = 'Updated', 'Coverage (overall)', 'last 24 hours', 'Deleted', 'Deleted last 24 hours', 'Banned', 'Banned last 24 hours'
sizes = (6, 5.04, 0, 12, 0, 7, 7)
colors = ['yellowgreen', 'gold', 'lightskyblue', 'green', 'black', 'red', 'grey']

def absolute_value(val):
    a  = numpy.round(val/100.*sizes.sum(), 0)
    return a

plt.pie(sizes, labels=labels, colors=colors,
        autopct=absolute_value)

plt.axis('equal')
plt.show()

Now the output:


AttributeError                            Traceback (most recent call last)

      9     a  = numpy.round(val/100.*sizes.sum(), 0)
     10     return a
---> 12 plt.pie(sizes, labels=labels, colors=colors,
     13         autopct=absolute_value)
     15 plt.axis('equal')
     16 plt.show()

AttributeError: 'tuple' object has no attribute 'sum'

I pasted the entire tracecall back hopefully to determine the error perfectly.

How can I fix that?

CodePudding user response：

Try out This code:

import matplotlib.pyplot as plt
import numpy

labels = ['Updated', 'Coverage (overall)', 'last 24 hours', 'Deleted', 'Deleted last 24 hours', 'Banned', 'Banned last 24 hours']
sizes = [6, 5.04, 0, 12, 0, 7, 7]
colors = ['yellowgreen', 'gold', 'lightskyblue', 'green', 'black', 'red', 'grey']

def absolute_value(val):
    a  = numpy.round(val/100*sizes.sum(), 0)
    return a

plt.pie(sizes, labels=labels, colors=colors)

plt.axis('equal')
plt.show()

You should use the sizes and colors as list
