Iteration Through tuple of dictionaries in Python

Question

I am trying to iterate through a tuple of dictionaries using Python, get the value that I'm looking for and then modify another dictionary with that value. Example:

Dict = {'1': 'one', '2': 'three'}

Tuple = ({'1': 'one', '5': 'five'}, {'4': 'four', '2': 'two'})

My goal is to modify Dict and replace 'three' with 'two' from my second dictionary in my tuple.

I know how to iterate through dictionaries using for loops and dict.items() , but i can't seem to do so with tuple...

Any help will be much appreciated!

Answer 1

Just check each dict d for the key and then set Dict["2"] equal to d["2"] .

Dict = {'1': 'one', '2': 'three'}

Tuple = ({'1': 'one', '5': 'five'}, {'4': 'four', '2': 'two'})

for d in Tuple:
    if "2" in d:
        Dict["2"] = d["2"]

If you have multiple dicts in Tuple that have the same key the value will be set to the last dict you encounter. If you wanted the first match you should break in the if.

Dict = {'1': 'one', '2': 'three'}

Tuple = ({'1': 'one', '5': 'five'}, {'4': 'four', '2': 'two'})
for d in Tuple:
    if "2" in d:
        Dict["2"] = d["2"]
        break # get first match

If you want the last match it would be better start at the end of Tuple:

for d in reversed(Tuple):
    if "2" in d:
        Dict["2"] = d["2"]
        break # last dict in Tuple that has the key
