Boto3 Object put method loads 0 bytes

The following loads an empty file to my s3 bucket. Why?

df = pd.DataFrame([[1,2,3],[324,34,25], [463,23,43]])
out = df.to_csv(index=False) # unicode string (i'm in python 3)

s3 = boto3.resource('s3')
BUCKET = "MyBucketThatDefExistsAndIHaveAccessTo"
bucket = s3.Bucket(BUCKET)
obj = bucket.Object('TEST1')
obj.put(df.to_csv(index=False)) # loads an empty file "TEST1" to my bucket.

# I've also tried, but same result.
obj.put(bytes(df.to_csv(index=False), 'utf8'))

I'm just dumb. Needs the Body= kwarg.

obj.put(Body=df.to_csv(index=False) works

Should it not be,

obj.put(Body=df.to_csv(index=False)) # loads an empty file "TEST1" to my bucket.

Missing Body named parameter. Since first parameter is ACL, you need to specify the name.

Hope it helps.
