Concatenation of multiple files with wildcard

I have the following snippet to concatenate about a hundred csv-files:
Code:
for file in *csv; do cat $file >> newfile; done

This line works, but before I was experimenting with the following line, which is more intuitive and is a tad more robust:
Code:
for file in *.csv; do cat $file >> newfile; done

Can someone tell me why the dot (.) leads to an error message?
Code:
#cat: *.csv: No such file or directory

Thanks in advance

virt-top --csv data.csv processcsv.py < data.csv DESCRIPTION
virt-top is a top(1)-like utility for showing stats of virtualized domains. processcsv.py is a simple Python script that post-processes the output of "virt-top --csv". It is used like this: virt-top --csv data.csv processcsv.py < data.csv The second command will overwrite the following files in the current directory: "global.csv" This contains the global (host) statistics columns from the CSV file. "domainNN.csv" (multiple files) For each libvirt domain ID NN, a file is created containing the per-domain statistics from the CSV file. SEE ALSO
