pandas dataframe apply lambda index error
I have the following code
df2['TaxAccNo4'] = df2['TaxAccNo2'].apply(lambda x: x.split('.')[0])
df2['TaxAccNo3'] = df2['TaxAccNo2'].apply(lambda x: x.split('.')[1])
where df2 is:
TaxAccNo2
0 00001379.1
1 00182218
When I run the code I get
TaxAccNo2 TaxAccNo4
0 00001379.1 00001379
1 00182218 00182218
and IndexError: list index out of range for TaxAccNo3,
TaxAccNo2 TaxAccNo4 TaxAccNo3
0 00001379.1 00001379 1
1 00182218 00182218
How do I fix my code to produce that output? I'm assuming its giving me the error because Index 1 doesn't have '.' but I'm not sure how to fix that.

As you said, the problem is that "00182218".split(".")
doesn't have a [1]
index, since it's the list ["00182218"]
.
A simple solution without affecting too much the code is to use a ... if ... else ... ternary operator:
df2['TaxAccNo4'] = df2['TaxAccNo2'].apply(lambda x: x.split('.')[0])
df2['TaxAccNo3'] = df2['TaxAccNo2'].apply(lambda x: x.split('.')[1] if '.' in x else '')
Where the last ''
is an empty string, the value with which you will fill 'TaxAccNo3' if 'TaxAccNo2' doesn't have a dot (you can replace it if you want other behaviour).
The semantic is: put x.split('.')[1]
in df2['TaxAccNo3']
if x
contains a dot, otherwise put an empty string.

Hy, I was reviewing your code, the problem is that when you use the method split() in a string the returned object is a list, and this is causing the index error, as you pointed. The solution I encountered if very simple, use a conditional in your code to prevent it from calling this index for shorter lists as follows. Hope it helps.
df2['TaxAccNo3'] = df2['TaxAccNo2'].apply(lambda x: x.split('.')[1] if len(x.split('.'))>1 else x)

A simple solution without affecting too much the code is to use a ... if ... else ... ternary operator:

df2['TaxAccNo3'] = df2['TaxAccNo2'].apply(lambda x: x.split('.')[1] if '.' in x else '')
Where the last ''
is an empty string, the value with which you will fill 'TaxAccNo3' if 'TaxAccNo2' doesn't have a dot (you can replace it if you want other behaviour).
The semantic is: put x.split('.')[1]
in df2['TaxAccNo3']
if x
contains a dot, otherwise put an empty string.
