This is a sample code:
var1 = float(input('Enter time interval: '))
print(f'OK, time interval is {var1}')
# doing something with above variable
I want to run this python file like this without changing the code if possible:
python file.py 0<'15'
But I get this error:
-bash: 15: No such file or directory
You can provide the input through a pipe:
echo 15 | python file.py
Or, with lesser known syntax, using process substitution, which I'm mentioning because it seems like this is what you were trying to do:
python file.py < <(echo 15)
In both cases, be aware of the shell's quoting rules and add quotes accordingly.
If there are multiple lines, a bash heredoc might be easier:
python file.py <<EOF
line1
line2
line3
EOF
You can do a
python file.py <<<15
The <<< redirection takes the string to its right and feeds it to the program as standard input.
