Python's handling of Unicode-character variables is surprising!
𝐀 = {'😀': 5}
for ℹ︎ in range(20):
# print(i, ℹ︎, i == ℹ︎) # NameError: name 'i' is not defined.
for _,__ in 𝐀.items():
if __ == ℹ︎:
print(_, ℹ︎)
print(𝐀) # Prints dictionary in 𝐀
print(A) # Also prints dictionary in 𝐀!
print(𝐀 is A) # True

lsloan / recursiveFormat.py

`recursiveFormat()` – Recursively apply `string.format()` to all strings in a data structure.
def recursiveFormat(args, **kwargs):
"""
Recursively apply `string.format()` to all strings in a data structure.
This is intended to be used on a data structure that may contain
format strings just before it is passed to `json.dump()` or `dumps()`.
Ideally, I'd like to build this into a subclass of `json.JsonEncoder`,
but it's tricky to separate out string handling in that class. I'll
continue to think about it.
