a straight forward way to solve this:


test = 'apple johnny seed'
for eachLetter in test: # eachLetter can be replaced with any other name
        if eachLetter in ['a','e','i','o','u']:
                test = test.replace(eachLetter, '')
print test

The good thing about Eclipse is that it suggests many things for you (such as methods, properties, etc) and you can run the python program in a console in the same window. Visually more aesthetic and all your files can be organized into a workspace that Eclipse makes. I would recommend making the workspace (where all your programs go and all) on your flash drive. This could slow it down (maybe) but it offers portability for Windows PCs or Macs that have Eclipse on them.

To get PyDev, download the new Eclipse (I recommend Java version because I use Java) and then download the new PyDev from here. Unzip both of them and then open the PyDev unzipped folder. There will be 2 folders that share the same name as the Eclipse unzipped folder. Take the contents of the PyDev folder and move them into the Eclipse folders.

Now when you open up Eclipse, enter where you want your workspace and then go to Window > Open Perspective > Other and then select PyDev. Only one more thing left to do – select Preferences under the “Eclipse” menu item (Command + ,). Add Python path and you’re done.

How to evaluate this? A simple int(equation) will not give you the answer of 10 that you want...

Answer: eval(equation) will give you the right answer.

Special newb Treatment:

# prints 10
print eval('1+2+3+4')


def main():
	try:
		while 1:
			print "hi"
	except KeyboardInterrupt:
		try:
			while 1:
				print "ho"
		except KeyboardInterrupt:
			try:
				while 1:
					print "ha"
			except KeyboardInterrupt:
				try:
					while 1:
						print "he"
				except KeyboardInterrupt:
					try:
						while 1:
							print "hu"
					except KeyboardInterrupt:
						while 1:
							print "eeek"

If you do not understand, here are the original instructions. Get your sample input files and expected answers from that link, too.

Reminder Hint: Reading in files are really easy and the way you read in files and get the data are various. One way to do it would be to read in all the data into one string (separate lines have the special character “\n” in them) and then split it by the special character “\n”.

f = open('anagramTesterData.dat')
data = f.read()
data = data.split('\n')

Answer Below:

answers = []

f = open('anagramTesterData.dat')
data = f.read()
data = data.split('\n')

original = data[0]
numberTests = data[2:len(data)]

for test in numberTests:
	i = 0
	if test == original:
		answers.append('IDENTICAL')
	else:
		temp = original
		temp = list(temp)
		for char in test:
			if char in temp:
				temp.remove(char)
			else:
				i = 1
				answers.append('NOT AN ANAGRAM')
				break
		if not (i == 1):
			answers.append('ANAGRAM')

print answers

Answer Below:

def removeVowel(phrase):
	vowels = 'AEIOUaeiou'
	final = ''	# two single quotes to indicate empty string
	for char in phrase:	# for each character
		if char not in vowels:
			final += char	     # string concatenation to add each letter that is not a vowel
	return final

First off, to create a module, create a regular .py file with many functions defined. For example:


# myfunctions.py
def doubleNum(x):
      return 2*x


Now, in a different file, instead of creating another doubleNum() function, just import this file.


from myfunctions import doubleNum
a = 2
print doubleNum(a)


Alternatively,


import myfunctions
a = 2
print myfunctions.doubleNum(a)


Kinda like myfunctions is an object and you’re using a method of that object.

I finished it and will most likely explain most of the code in a subsequent update.

Code [file: anagramTester.py]:

# http://www.compapp.dcu.ie/~cdaly/ire_comp/ire01/problems/prob1.html
# Tests whether strings are anagrams of a given word
answers = []

f = open('anagramTesterData.dat')
data = f.read()
data = data.split('\n')

original = data[0]
numberTests = data[2:len(data)]

for test in numberTests:
i = 0
if test == original:
answers.append('IDENTICAL')
else:
temp = original
temp = list(temp)
for char in test:
if char in temp:
temp.remove(char)
else:
i = 1
answers.append('NOT AN ANAGRAM')
break
if not (i == 1):
answers.append('ANAGRAM')

print answers

To test if it works [file: anagramTesterData.dat]:
cares
5
scare
races
cares
another
acres

With expected (correct) output:
ANAGRAM
ANAGRAM
IDENTICAL
NOT AN ANAGRAM
ANAGRAM
