Suppose you have a string that is used twice in one string. However, in one case it is upper, and the other it is lower. If a dictionary is used, it would seem the solution would be to add a new element that is uppercase.
Suppose I have a python string ready to be formatted as:
string = "{a}_{b}_{c}_{a}"
With a desired output of:
HELLO_by_hi_hello
I also have a dictionary ready as:
dictionary = {a: "hello", b: "bye", c: "hi"}
Without interacting with the dictionary to set a new element d as being "HELLO" such as:
dictionary['d'] = dictionary['a'].upper()
string = "{d}_{b}_{c}_{a}"
string.format(**dictionary)
print(string)
>>> HELLO_bye_hi_hello
Is there a way to set element a to always be uppercase in one case of the string? For example something like:
string= "{a:upper}_{b}_{c}_{a}"
string.format(**dictionary)
print(string)
>>> HELLO_bye_hi_hello
Yes, you can do that:
string = "{d.upper()}_{b.lower()}_{c.lower()}_{a.lower()}"
