Sum values in a list in pandas data

i am a newbie in python and need your support. I have a below output from test data frame 

     LS    last  height weight
0   88+2    Doe  5.5    130
1   90+2    Bo   6.0    150

output[]

0    [88, 2]
1    [90, 2]

I'm trying to sum the values in the 'LS' column. is the output for LS columns should be sum ie 90 & 92. I split them into a list and trying to sum them

Can you please suggest how to proceed?

We can try eval 

df.LS=pd.eval(df.LS)
#pd.eval(df.LS)
#Out[394]: [90, 92]

Try this:

df = pd.DataFrame({
    'LS': [[88, 2], [90,2]]
})
df['sum'] = df['LS'].apply(sum)
print(df)

        LS  sum
0  [88, 2]   90
1  [90, 2]   92
