Hi there,
I am a new python user.
I have a question regarding do loop.
This is a simple program that I have written:
-
N=10
h=10.0 # [micrometer]
z=-200.0 # [micrometer]
num = 0.05 #m**2/s
dz = 1.0
nuh=[]
tmax=3600
dt=20.
nu=[]height = arange(z*dz,0,dz)

Sue,
I'm not familiar with FORTRAN, and since I'm not completely sure what you're
trying to accomplish please take this simply as an 'educated guess'.
My guess is that you're not getting the curve because Z is only defined to one
decimal location (1/10th) precision and probably needs higher p
for key, value in pairs.items():
if key[::-1] in pairs.keys() and pairs[key] != 0:
pairs[key] += pairs[key[::-1]]
pairs[key[::-1]]=0
for k, v in pairs.items():
if v != 0:
print(v,k)
Now very trivial, but works.
regarding to the last email:
what I am trying to do is seeing the variation of 'nu' over (changes of) 'z'.
My concern is how to arrange this!
Basically, I am not able to define the variation of nu by z ( 1 to
200). I am looking for a statement to show the changes of 'nu' for
each step of z (

I don't get this "pairs.get" part.
The "get" method does a look-up on a dict, but instead of failing if the
key is missing, it returns a default val

A web site that you can paste stuff and then provide a link(url) that

You can usually specify the code style
