Python 3, unsupported operand type(s) for -: 'str' and 'str'

Question

I am freshman in this sphere, so please help.

import pygal
line_chart = pygal.Line()
line_chart.title="Chart"
line_chart.x_labels = ['Jan', 'Feb', 'Mar', 'April', 'May']
print('Enter a type of social media: ')
a=input()
print('Enter 5 values of '+a,': ')
b=list(input())
line_chart.add(a, b)
line_chart.render_in_browser()

Exception has occurred: TypeError unsupported operand type(s) for -: 'str' and 'str' this error is appearing in front of line_chart.render_in_browser() this code

Answer 1

You are pushing str type of data into your chart.

You have to convert your input type. The line chard would work on int , float or decimal type for number.

import pygal 
line_chart = pygal.Line() 
line_chart.title="Chart" 
line_chart.x_labels = ['Jan', 'Feb', 'Mar', 'April', 'May'] 
print('Enter a type of social media: ') 
a=input() 
print('Enter 5 values of '+a,': ') 
b=map(int, input().split())
line_chart.add(a, list(b)) 
line_chart.render_in_browser()
