New submission from Aschwin <[email protected]>:
I expected the custom Formatter to behave the same as the normal "".format()
function, but unnamed args or not supported.
Below is an example, which fails at a KeyError.
from string import Formatter
class test():
def __init__(self):
self.msg = "OK"
t = test()
print("Normal format() is {.msg}".format(t))
f = Formatter()
print(f.format("Formatter.format() is {.msg}", t))
