I usually do this in Perl:
whatever.pl
while(<>) {
#do whatever;
}
then cat foo.txt | whatever.pl
Now, I want to do this in Python. I tried sys.stdin but I have no idea how to do as I have done in Perl. How can I read the input?

To loop through a directory, and then print the name of the file, execute the following command: for FILE in *; do echo $FILE; done.
The syntax to loop through each file individually in a loop is: create a variable (f for file, for example). Then define the data set you want the variable to cycle through. In this case, cycle through all files in the current directory using the * wildcard character (the * wildcard matches everything).
The Windows command prompt (cmd.exe) allows the ^ (Shift + 6) character to be used to indicate line continuation. It can be used both from the normal command prompt (which will actually prompt the user for more input if used) and within a batch file.
Try this:
import fileinput
for line in fileinput.input():
process(line)
