filtering a dataframe with uuids returns an empty result
Question:
I have this data frame:
df:
id
hint
29c45630-7d41-11e9-8ea2-9f2bfe5760ab
None
61afc910-3918-11ea-b078-93fcef773138
Yes
and I want to find the first row that has this id = 29c45630-7d41-11e9-8ea2-9f2bfe5760ab
when I run this code:
df[df['id'] == '29c45630-7d41-11e9-8ea2-9f2bfe5760ab']
return empty!!! and the type of this id is "object"
but I really have this id!!
how can I find it?
Answers:
You have to use property DataFrame.loc[source], read here
df.loc[df['id'] == '29c45630-7d41-11e9-8ea2-9f2bfe5760ab']
You code didn’t work because you have UUIDs, not strings, you first need to convert to string:
df[df['id'].astype(str).eq('29c45630-7d41-11e9-8ea2-9f2bfe5760ab')]
Output:
id hint
0 29c45630-7d41-11e9-8ea2-9f2bfe5760ab None
I have this data frame:
df:
| id | hint |
|---|---|
| 29c45630-7d41-11e9-8ea2-9f2bfe5760ab | None |
| 61afc910-3918-11ea-b078-93fcef773138 | Yes |
