+# string.Template
+
+Published: 2022-09-20.
+
+The [string.Template](https://docs.python.org/3/library/string.html#template-strings) class allows to do `$`-style substitutions:
+
+```python
+from string import Template
+t = Template('Hello, $channel!')
+
+t.substitute(dict(channel='@pythonetc'))
+# 'Hello, @pythonetc!'
+
+t.safe_substitute(dict())
+# 'Hello, $channel!'
+```
+
+Initially, it [was introduced](https://peps.python.org/pep-0292/) to simplify translations of strings. However, now [PO-files](https://www.gnu.org/software/gettext/manual/html_node/PO-Files.html) natively support [python-format](https://www.gnu.org/software/gettext/manual/html_node/python_002dformat.html) flag. It indicates for translators that the string has `str.format`-style substitutions. And on top of that, `str.format` is much more powerful and flexible.
+
+Nowadays, the main purpose of `Template` is to confuse newbies with [one more way to format a string](https://t.me/pythonetc/610). Jokes aside, there are a few more cases when it can come in handy:
+
++ `Template.safe_substitute` can be used when the template might have variables that aren't defined and should be ignored.
++ The substitution format is similar to the string substitution in bash (and other shells), which is useful in some cases. For instance, if you want to write your own [dotenv](https://github.com/motdotla/dotenv).

 # warnings
 
+Published: 2022-09-13.

 The module [warnings](https://docs.python.org/3/library/warnings.html) allows to print, you've guessed it, warnings. Most often, it is used to warn users of a library that the module, function, or argument they use is deprecated.
