\$\{([^{}]+)\} (flags: g)Python (re) code

import re
pattern = re.compile(r"\$\{([^{}]+)\}")
input_text = "`Hello ${name}, you have ${count} items`"
for m in pattern.finditer(input_text):
print(m.group(0))Stdlib `re` module — no third-party dependency. Works on Python 3.6+.
How the pattern works
\$ matches the dollar sign. \{ matches the opening brace. ([^{}]+) captures one or more non-brace characters as the inner expression. \} matches the closing brace. The pattern won't handle nested braces (e.g. `${ {a:1}.a }`); for that you need a real parser, but this regex covers the common case.
Examples
Input
`Hello ${name}, you have ${count} items`Matches
${name}${count}
