ValueError: shape mismatch: objects cannot be broadcast to a single shape

This is an error that occurred while studying graph display on juoyter-notebook.

I want to display a simple bar graph with vertical (value) 1 ~ 6 and horizontal (y_pos) a ~ f.

code

error

Translated literally ValueError: Shape mismatch: Object cannot be broadcast to a single shape

What seems to be a discrepancy is about the defined value? Go to see the value, 1, 2, 3, 4, 5, 6 a, b, c, d, f e is missing! !!

Resolution code

Add'e'and succeed

Display successful
