Jinja Templates - Format a float as comma-separated currency

Question

I\'m trying to format a float as comma-separated currency. E.g. 543921.9354 becomes $543,921.94. I\'m using the format filter in Jinja t

Answer 1

Python3.6:

def numberFormat(value):
    return format(int(value), ',d')

Flask global filter

@app.template_filter()
def numberFormat(value):
    return format(int(value), ',d')

Flask global filter for Blueprint

@app.app_template_filter()
def numberFormat(value):
    return format(int(value), ',d')

Call this global filter

{{ '1234567' | numberFormat }}
#prints 1,234,567

Calling it in Jinja without assigning a global filter

{{ format('1234567', ',d') }}
#prints 1,234,567
