More examples:

# a multiconditional statement
if x > 0:
  if x < 10:
    print("x is larger than zero and less than 10")

# a simpler version
if 0 < x < 10:
  print("x is larger than zero and less than 10")

# is character lower case?
if 'a' <= character <= 'z':
  print(character)

Use list slicing and extend().
Hint:

mylist = [0,1,2,3,4,5,6,7,8,9]
ix = 3

t1 = mylist[0:ix]
t2 = mylist[ix+1:]

# now use list extend()
t2.extend(t1)

print(t2)  # [4, 5, 6, 7, 8, 9, 0, 1, 2]

Python has all the tools to do such a thing.

Use slice and extend(), for example:

mylist1 = [1,2,3]
mylist2 = ['a','b','c']

# slice mylist into two temporary lists at index 2
t1 = mylist1[0:2]
t2 = mylist1[2:]

# now use list extend()
t1.extend(mylist2)
t1.extend(t2)

print(t1)  # [1, 2, 'a', 'b', 'c', 3]

The IPython Notebook seems to be made for scientific presentations and reports.
To show off things like numpy, matplotlib.pyplot, pylab, seaborn and guiqwt.pyplot. You can tweak your code and see the result in real time.

The strontium clock developed in the US would only have lost only about one second since the earth began. It is accurate to a second in five billion years.

Caesium was discovered in 1860 by German scientists Robert Bunsen and Gustav Kirchhoff. It's a silvery metal with a golden cast that melts at 28.4C (just above room temperature).

It is used in the Caesium Clock at the National Physical Laboratory in the London suburb of Teddington. The clock is accurate to one second in 1.4 million years.

I agree with JorgeM, real world examples/projects are important to keep the students interested.

An IDE like PyScripter would redline line 11 because of the missing comma.

You can also streamline your code further with another function to remove some of the repetition:

def main():
    shipweight = float(input('Please enter the weight of the item you wish to ship: '))
    shipping_charges(shipweight)

def shipping_charges_calc(rate, shipweight):
    print("{} pounds will cost you ${:0.2f} per pound.".format(shipweight, rate))
    total= rate * shipweight
    print("Therefore, your total shipping charge would be ${:0.2f}".format(total))

def shipping_charges(shipweight):
    if shipweight <= 2:
        rate=1.10
    elif shipweight <= 6:
        rate=2.20
    elif shipweight <= 10:
        rate=3.70
    # shipweight > 10 pounds
    else:
        rate=3.80
    shipping_charges_calc(rate, shipweight)

main()

Also read up on the function format(), commonly used with Python 2.7 and higher.

Nice coding though.
