from jinja2 import Environment # Create a Jinja2 environment object env = Environment()
from jinja2 import Environment # Define a custom filter function def reverse_filter(value): return value[::-1] # Create a Jinja2 environment object env = Environment() # Add the custom filter to the environment object env.filters['reverse'] = reverse_filter
from jinja2 import Environment # Create a Jinja2 environment object with custom syntax env = Environment(block_start_string='~{', block_end_string='}~', variable_start_string='~{{', variable_end_string='}}~') # Define a template that uses the custom syntax template = env.from_string('~{for item in items}~\n~{{item}}~\n~{endfor}~') # Render the template with a list of items output = template.render(items=['apple', 'banana', 'orange']) print(output) # Output: # apple # banana # orangeIn summary, the jinja2.environment Environment package library provides a wide range of utility methods and properties for customizing the behavior of the Jinja2 template engine. It is an essential tool for building dynamic web applications in Python.
