Modifying regex to not allow spaces

I have this regex that matches any string that contains one or more letters followed by one or more numbers

[A-Za-z].*[0-9]

I'd like to modify this to not allow spaces, which looks like can be done with [^ ]

I've tried several different ways to modify my existing regex, but nothing seems to work, it always allows spaces in my string. I've tried these:

[A-Za-z].*[0-9]+[^ ]

[A-Za-z].*[0-9].+[^ ]

[A-Za-z].*[0-9].*[^ ]

What's the right way for me to do that?

`^[A-Za-z][^ ]*[0-9]$`, `^[A-Za-z]\S*[0-9]$`... Maybe the anchors are not necessary. – Wiktor Stribiżew Oct 23 '19 at 18:29

Use a quantifier `+` for the character classes to repeat 1+ times `^[A-Za-z]+[0-9]+$` – The fourth bird Oct 23 '19 at 18:30
It is worth pointing out to the OP that the reason the regexes in the post don't work is that dot `.` matches any character, including a white space character. – iakobski Oct 23 '19 at 20:23
