Several places in your README file you have referred to
the README.md under /bigquery
while there is no such a file here: https://github.com/GoogleCloudPlatform/python-docs-samples/tree/master/bigquery
Are you referring to somewhere else or the file is moved to another place?
The file's been moved, I'll update those samples.
Fixed in I05013e56
Thank you so much @jonparrott
The same applies to api
I updated all references to README within the bigquery folder, including api. :)
In my opinion it would have been better to remove that line, instead of referring to itself! :-)
It's a little misleading, but the readmes are generated from the help output of the samples. So they reference each other. :)
