When you used json.loads(), there was no way for Python to know that the string key should be an integer again. That’s why your dictionary key remained a string after deserialization.You’ll investigate a similar behavior by doing another conversion roundtrip with other Python data types!
# Example of using string modulo operator(%) # with print() function name = "Alex" age = 21 perc = 89.99 # printing all values print("Name : %s, Age : %d, Percentage : %.2f" % (name, age, perc)) # integer padding print("%5d\n%5d\n%5d" % (1, 11, 111)) # printing ...
