Hey, guys!
Found out anouther one tricky stuff in quiz lib and in python indeed.
Look at the following code:
lst = [34,67,45]
print(lst.sort()==sorted(lst))
Right answer is surprisingly False! Surprisingly because if put inplace sort operation before comparision like here:
lst = [34,67,45]
lst.sort()
print(lst==sorted(lst))
https://code.sololearn.com/crzl8w9LBbBd
the output is True!
Does anybode know how it is working? Why lst.sort()==sorted(lst) is False actually?
sort changes the original list by sortsing it but does NOT return a new list
sorted does not change the original list but returns a new sorted list
basically what it translated to is None==sorted(lst) as sort does not returns anything
just try this:
print(lst.sort())
print(sorted(lst))
and post your results here
@sayan chandra
list.sort() works by changing the list object
so no need for it to return anything
same way as if you declare a function that does not return anything and print its output
def foo():
x = 1
print(foo()) # outputs None
