template — Simple String Templates¶

The template module provides {{key}} placeholder substitution and HTML escaping.

Import¶

import template

API Reference¶

Function	Description
`template.render(tmpl, keys, values)`	Render `{{key}}` placeholders
`template.render_pairs(tmpl, pairs)`	Render with `[k1, v1, k2, v2, ...]` list
`template.escape_html(input)`	Escape `&`, `<`, `>`, `"`, `'`

Examples¶

Basic rendering¶

import template

let result = template.render(
    "Hello, {{name}}! Welcome to {{city}}.",
    ["name", "city"],
    ["Alice", "Wonderland"]
)
print(result)
# Hello, Alice! Welcome to Wonderland.

Render with pairs¶

import template

let msg = template.render_pairs(
    "{{greeting}}, {{who}}!",
    ["greeting", "Hi", "who", "World"]
)
print(msg)  # Hi, World!

Unknown keys are preserved¶

import template

let result = template.render(
    "{{known}} and {{missing}}",
    ["known"],
    ["found"]
)
print(result)  # found and {{missing}}

HTML escaping¶

import template

let safe = template.escape_html("<script>alert('xss')</script>")
print(safe)
# &lt;script&gt;alert(&#39;xss&#39;)&lt;/script&gt;

Features¶

Mustache-style {{key}} placeholders
Whitespace tolerant — {{ name }} works too
Safe by default — unknown keys preserved, not silently removed
HTML escaping — prevent XSS in web templates
