p=('99','655','864','654')

why is 99 at last? It should be first.

A=["asd","jkl","qwe"]
[A[1:3],A[0:1]]
gives
[['jkl', 'qwe'], ['asd']]
I wish it just gave
['jkl', 'qwe', 'asd']
How do I accomplish this seemingly elusive task?
edit: the version of python I must work with does not allow for * symbol.
A=["asd","jkl","qwe"]
A = [*A[1:3], *A[0:1]]

This is my code but my output gives a none type back and not a list full of numbers.
PHC=[]
for i in range(len(df)):
x=df['HC'][0:i+1].mean()
PHC=PHC.append(x)
len[df]['HC']
instead of
len[df]

Python list sort in descending order
(6 answers)
Closed 4 years ago.
The code I have is:
sAreaOfCountries=sorted(aOfCountries.items(),key=operator.itemgetter(1))
But this sorts from least to greatest. How would I sort from greatest to least?
sorted has an argument called reverse.
sAreaOfCountries=sorted(aOfCountries.items(),key=operator.itemgetter(1),reverse=True)

This is my code:
#这是一个有关旅行的程序
place=['北京天安门','西安兵马俑','香港游乐园','日本秋叶原']
print(place)
print(sorted(place))
print(place)
place.sorted(reverse=true)
print(place)
When I run my code, something Wrong happens.
place.sorted(reverse=true)
or
sorted(place)
Using the 2nd way, how can I give (reverse=true)?
Just use sorted(place, reverse=True).
