Result value
{}
-------------------------------------------------

fruits_dic={'apple':6000,'melon':3000,'banana':5000,'orange':7000}

print(fruits_dic.clear())

Result value
None

This is because the clear command is not a command to spit out the result value.

fruits_dic={'apple':6000,'melon':3000,'banana':5000,'orange':7000}
a = fruits_dic.clear()
print(a)
print(fruits_dic)
>> None
{}

fruits_dic={'apple':6000,'melon':3000,'banana':5000,'orange':7000}
print(fruits_dic.clear())
print(fruits_dic)
>> None
{}
