Hello,

I am beginner in python. I am trying to draw districution curve using one column (total_time) from my csv file. I am getting error on line 13 in this code. Any help will be highly appreciated.

import csv

from sortedcontainers import SortedDict

import matplotlib.pyplot as plt

import numpy as np

import scipy.stats as stats

import matplotlib.pyplot as plt

d = {}

with open(‘C:\Users\dreamzz\myfile.csv’, ‘rb’) as csvfile:

reader = csv.DictReader(csvfile)

for col in reader:

field = col[‘Total_time’]

for i in field:

if d[1]== ’ ’ :

```
d[1]=i
else:
d[1]=i+1
s = SortedDict(d)
hmean = np.mean(s)
hstd = np.std(s)
pdf = stats.norm.pdf(s, hmean, hstd)
plt.plot(s, pdf)
```
