'DataFrame' object has no attribute 'string_column'

I am trying to count the delimiter from my CSV file using this piece of code:

import pandas as pd

df = pd.read_csv(path,sep=',')
df['comma_count'] = df.string_column.str.count(',')
print (df)

But I keep getting this error: 'DataFrame' object has no attribute 'string_column'. Trying to iterate through my dataframe had no avail.

I am trying to achieve this:

     id    val      new  comma_count
     id    val      new          2
0     a    2.0    234.0          2
1     a    5.0    432.0          2
2     a    4.0    234.0          2
3     a    2.0  23423.0          2
4     a    9.0    324.0          2
5     a    7.0      NaN          1
6   NaN  234.0      NaN          1
7     a    6.0      NaN          1
8     4    NaN      NaN          0

My file:

id,val,new
a,2,234
a,5,432
a,4,234
a,2,23423
a,9,324
a,7
,234
a,6,
4

Use different separator with select first column and count:

df1 = pd.read_csv(path,sep='|')
df['dot_count'] = df1.iloc[:, 0].str.count(',')
