Solving a formula with decimal values of x and plotting the results
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty height:90px;width:728px;box-sizing:border-box;

I try to obtain y for x values [250.5(first), 50.5(last), -10(increment)]:
y = 100 * exp(-5000/x)
and, then, plot it. I did
import numpy as np
import matplotlib.pyplot as plt
for i in numpy.arange(250.5, 50.5, -10):
print(i, 100 * exp(-5000/i))
plt.plot(i, y)
plt.show()
But it gets error as:
NameError: name 'numpy' is not defined
I appreciate if someone could help me.
Thanks.

You've imported numpy as np, but in the code you are usingnumpy.arange, you need to change this tonp.arange

But I still don't get any plot. Do you know how I can solve this.

There are too many errors in the code to go through them one by one.
To plot the curve you want you would evaluate the function you have on an array.
import numpy as np
import matplotlib.pyplot as plt
x = np.arange(250.5, 50.5, -10)
y = 100 * np.exp(-5000/x)
plt.plot(x, y)
plt.show()
