How to convert my stats calculated array to 2 decimals?

Question

The following line of code prints the standard deviation and mean on my graph using matplotlib in python. My question is. How do I convert the values to 2 decimals?

ax.text(60, 0.01, r'$\mu={},\ \sigma={}$'.format(np.mean(stat_input),np.std(stat_input)))

Can you elaborate on what you mean by "2 decimals"? What are you currently getting, and what do you want to get? — Linuxios, May 14 '17 at 17:08
I get mu = 54.38493289325 and Sigma = 48.48389489348 I would like 54.38 and 48.48 — ShibbyBoss, May 14 '17 at 17:15

>>> '{:.2f}'.format(123.456789)
'123.46'

For details see: Format String Syntax

So, in your case the line becomes:

ax.text(60, 0.01, r'$\mu={:.2f},\ \sigma={:.2f}$'.format(
    np.mean(stat_input), np.std(stat_input)
))

I get this. I don't know how to incorporate it into the line of code that I wrote. I am not a python pro, I am a beginner. – ShibbyBoss May 14 '17 at 17:21
@ShibbyBoss updated. You can use this syntax inside the `{}` – Igonato May 14 '17 at 17:24
Ahhh, I understand now. I tried something similar but was missing a character. Thank you – ShibbyBoss May 14 '17 at 17:38
