Round off dict values to 2 decimals

Question

I\'m having a hard time rounding off values in dicts. What I have is a list of dicts like this:

y = [{\'a\': 80.0, \'b\': 0.0786235, \'c\': 10.0, \'d\': 10.6         


        

Answer 1

import json


y = [{'a': 80.0, 'b': 0.0786235, 'c': 10.0, 'd': 10.6742903}, {'a': 80.73246, 'b': 0.0, 'c':   
10.780323, 'd': 10.0}, {'a': 80.7239, 'b': 0.7823640, 'c': 10.0, 'd': 10.0}, {'a': 
80.7802313217234, 'b': 0.0, 'c': 10.0, 'd': 10.9762304}]

def roundingVals_toTwoDeci(y):

    for d in y:
        for k, v in d.items():
            v = round(v,2) # <--- round() does exact that.
            d[k] = v # <--- You need to put the rounded v back in d
            print v
    return

roundingVals_toTwoDeci(y)
s = json.dumps(y)
print s
