python - Sed to remove everything after "." in file using * command? -

i have following data.txt:

 95 flour.  47 water.s  etc..

i need remove after period . in file yield this:

 95 flour  47 water  etc..

i have tried using these sed command without success, yield blank document:

sed "s/'.*//" data.txt > cleaned.txt  sed 's/\.*//' data.txt > cleaned.txt

either escape . backslash literal ., or use brackets define character class:

sed 's/\..*$//' data.txt > cleaned.txt sed 's/[.].*$//' data.txt > cleaned.txt

you tried 's/\.*//', "zero or more literal dots", different "literal dot followed 0 or more of anything", i.e. 's/\..*//'. added $ measure.
