Vector Calculations in Pandas

I have CSV file with Vector3 values exported from a C# program. I would like to use vector operations (like calculating the distance etc.) in pandas.
As far as I have seen, there is no Vector3 type in pandas. np.array offers this kind of operations but it is not available in pandas. What is the easiest way to accomplish vector calculations in a dataframe like data structure?
I would appreciate a detailed description starting with how to import the records from the CSV file as a vector type and ending with a calculation example.
The csv file has the following format:

aBin, bBin1, bBin2, bBin3, bBin4, ...
1, "(-1.6831280, 0.0000000, 2.4093440)", "(0.9445564, 0.0000000, 1.9509810)", "(-1.6831280, 0.0000000, 2.4093440)", "(0.9445564, 0.0000000, 1.9509810)" ...
2, "(-5.6848290, 0.0000000, 2.7744440)", "(0.6555564, 0.0000000, 7.2209800)", "(-3.6818280, 0.0000000, 2.5663330)", "(0.6445564, 0.0000000, 2.9509810)" ...
...

Edit
This CSV contains measurements of a program. There is a similar CSV (same shape) of another program and I want to calculate the distances between those two CSV (e.g. the distance between the value of [aBin1][bBin1] of the first CSV with [aBin1][bBin1] of the second CSV). Finally I want to sum this distances to a single value.

Solution

# vector1.txt
aBin, bBin1, bBin2
1, "(-1.6831280, 0.0000000, 2.4093440)", "(0.9445564, 0.0000000, 1.9509810)"
2, "(-5.6848290, 0.0000000, 2.7744440)", "(0.6555564, 0.0000000, 7.2209800)"

# vector2.txt
aBin, bBin1, bBin2
1, "(-1.6831280, 1.0000000, 2.4093440)", "(0.9445564, 2.0000000, 1.9509810)"
2, "(-5.6848290, 3.0000000, 2.7744440)", "(0.6555564, 4.0000000, 7.2209800)"

First, I loaded two files with file_to_dataframe function.

import numpy as np
import pandas as pd


def file_to_dataframe(fpath):
    # Function to change the format of file -> DataFrame
    # You can skip it if you can load the file as DataFrame
    with open(fpath, "r") as f:
        columns = f.readline().rstrip().split(', ')[1:]
        df = pd.DataFrame(columns=columns)
        for line in f:
            row = [x.replace('"', '') for x in line.rstrip().split(', "')[1:]]
            df = df.append(pd.Series(row, index=columns), ignore_index=True)
    return df.applymap(lambda x: np.array(eval(x)))

# Read file
df1 = file_to_dataframe('data/vector1.txt')
df2 = file_to_dataframe('data/vector2.txt')

>>df1
                        bBin1                       bBin2
0  [-1.683128, 0.0, 2.409344]  [0.9445564, 0.0, 1.950981]
1  [-5.684829, 0.0, 2.774444]   [0.6555564, 0.0, 7.22098]
>>df2
                        bBin1                       bBin2
0  [-1.683128, 1.0, 2.409344]  [0.9445564, 2.0, 1.950981]
1  [-5.684829, 3.0, 2.774444]   [0.6555564, 4.0, 7.22098]

And I got dist with np.linalg.norm function with flatten data from dataframe. and I made DataFrame with the result.

def dist(x, y):
    # https://stackoverflow.com/questions/1401712/how-can-the-euclidean-distance-be-calculated-with-numpy
    return np.linalg.norm(x-y)


new_vals = [dist(x, y) for x, y in zip(df1.values.flat, df2.values.flat)]
df_dist = pd.DataFrame(np.array(new_vals).reshape(df1.shape), columns=df1.columns, )

>>df_dist
   bBin1  bBin2
0    1.0    2.0
1    3.0    4.0
