How can I sort a dictionary by key?

Question

What would be a nice way to go from `{2:3, 1:89, 4:5, 3:0}` to `{1:89, 2:3, 3:0, 4:5}`? I checked some posts but they all use the "sorted" operator that returns tuples.

Answer 1

# This isn't really something people typically do, since

# you can simply sort the keys and then access the dictionary

# as if it's sorted, but here's an example of creating a dict

# y that is the sorted version of the dict x.

x={2:3, 1:89, 4:5, 3:0}

y={}

for key in sorted([key for key in x]):

y[key]=x[key]

print(x) # {2: 3, 1: 89, 4: 5, 3: 0}

print(y) # {1: 89, 2: 3, 3: 0, 4: 5}
