Is it possible to replace all values in a dictionary, regardless of value, with the integer 1?
Thank you!

Append values to a dictionary using the update() method The Python dictionary offers an update() method that allows us to append a dictionary to another dictionary. The update() method automatically overwrites the values of any existing keys with the new ones.
To replace words in a string using a dictionary: Use a for loop to iterate over the dictionary's items. Use the str. replace() method to replace words in the string with the dictionary's items.
Adding or updating nested dictionary items is easy. Just refer to the item by its key and assign a value. If the key is already present in the dictionary, its value is replaced by the new one. If the key is new, it is added to the dictionary with its value.
You can use df. replace({"Courses": dict}) to remap/replace values in pandas DataFrame with Dictionary values. It allows you the flexibility to replace the column values with regular expressions for regex substitutions.
Sure, you can do something like:
d = {x: 1 for x in d}
That creates a new dictionary d that maps every key in d (the old one) to 1.

You can use a dict comprehension (as others have said) to create a new dictionary with the same keys as the old dictionary, or, if you need to do the whole thing in place:
for k in d:
d[k] = 1
If you're really fond of 1-liners, you can do it in place using update:
d.update( (k,1) for k in d )
