since strings data types have variable length, it is by default stored as object dtype. If you want to store them as string type, you can do something like this.

df['column'] = df['column'].astype('|S80') #where the max length is set at 80 bytes,

or alternatively

df['column'] = df['column'].astype('|S') # which will by default set the length to the max len it encounters

Unable to convert a pandas object to a string in my DataFrame
object is just the dtype pandas uses for columns that contain values of type str (and many other Python types). The actual values themselves are still strings: import pandas as pd df = pd.DataFrame([["hello"], ["world"]], columns=["words"]) df.dtypes >>> words object dtype: object type(df.loc[0, "words"]) >>> Using .astype(str) does convert all values to string if they aren't already, but it doesn't change the column dtype by design. The only way around this is to use pandas's own string type via .astype("string"), but that's different from the str type, obviously. What exactly are the issues you are facing with the API?

r/learnpython on Reddit: Unable to convert a pandas object to a string in my DataFrame
December 10, 2021 -

Trying to use the YouTube API to pull through some videos for data analysis and am currently using just two videos in a dataframe to play around with the functionality as I'm new to all of this.

I'm using another API to get the transcripts for each video but I need to input the video_id into that API to get transcripts for each video.

The only problem is everything is stored as an object and whenever I try .astype(str) or something like that, it still says the data is an object and means I can't do anything with the data when a string is a required argument for the other API

This is what I get when calling .info() on my dataframe:

<class 'pandas.core.frame.DataFrame'>
RangeIndex: 2 entries, 0 to 1
Data columns (total 10 columns):
 #   Column                Non-Null Count  Dtype 
---  ------                --------------  ----- 
 0   video_id              2 non-null      object
 1   publishedAt           2 non-null      object
 2   channelId             2 non-null      object
 3   title                 2 non-null      object
 4   description           2 non-null      object
 5   channelTitle          2 non-null      object
 6   tags                  2 non-null      object
 7   categoryId            2 non-null      object
 8   liveBroadcastContent  2 non-null      object
 9   defaultAudioLanguage  2 non-null      object
dtypes: object(10)
memory usage: 288.0+ bytes

Any help would be really appreciated or an explanation of how these issues are usually handled

In this new DataFrame, you can see a b in front of the values in the column x2. The b stands for bytes, and you can learn more about this here. However, let’s check the dtypes of our updated DataFrame columns: print(data.dtypes) # Print data types of columns # x1 int64 # x2 |S1 # x3 int64 # dtype: object · The column x2 has been converted to the |S1 class (which stands for strings with a length of 1).
