invalid syntax error, what do i do?

Question

New to python. Can't seem to get this to work...

print = 'Press "U" and "Enter" for upper case.'
print = 'Press "L" and "Enter" for lower case.'
print = 'Press "C" and "Enter" for Capitalisation.'

letter = input("Please type a letter and press enter: ")
if letter == u: print '"THE MOST PROFOUND TECHNOLOGIES ARE THOSE THAT DISAPPEAR: THEY     WEAVE THEMSELVES INTO FABRIC OF EVERYDAY LIFE UNTIL ARE INDISTINGUISHABLE FROM IT" [MARK     WEISER, THE COMPUTER FOR THE 21ST CENTURY, SCIENTIFIC AMERICAN, SEPT. 1991]'
if letter == l: print '"the most profound technologies are those that disappear: they     weave themselves into fabric of everyday life until are indistinguishable from it" [mark weiser, the computer for the 21st century, scientific american, sept. 1991]'
if letter == c: print '"The most profound technologies are those that disappear: they weave themselves into fabric of everyday life until are indistinguishable from it" [Mark Weiser, The Computer for the 21st Century, Scientific American, Sept. 1991]'

also how can I improve the program so that the user can replace a one word with another word.

Use `print` as a function in py3.x and don't use it as a variable name. — Ashwini Chaudhary, Sep 05 '13 at 15:03

When you say new to python, which document or tutorial are you reading? Or are you going by "trial and error" learning? — rantanplan, Sep 05 '13 at 15:06
You probably also want to have a look at `string.lower()` and `string.upper()`... — tobias_k, Sep 05 '13 at 15:07
trail and error since the tutorial the school gave me was before 2.6 and the download link was for 3.3.2... — FluffySnot, Sep 05 '13 at 15:08
When you get a syntax error, it prints the line number of the error. That will usually help you in debugging your issue. — SethMMorton, Sep 05 '13 at 18:07

Should say

print('Press "U" and "Enter" for upper case.')
print('Press "L" and "Enter" for lower case.')
print('Press "C" and "Enter" for Capitalisation.')

I'd recommend using pythons string.replace function for replacing strings :)

also you should probably be using a function like upper() on your user input to account for both lower and upper case values:

if letter.upper() == U ........

how where would i use this? – FluffySnot Sep 05 '13 at 15:24
on the next couple lines after this: `letter = input("Please type a letter and press enter: ")` It will take the value of whatever they press, and convert it to upper case, so it will be consistent no matter if they type in lower case or upper case at the prompt. Note that you should then of course, be checking against upper case values for the letters. – user2366842 Sep 05 '13 at 16:03

Maybe something like

formats = {"U": {"text": "upper case", "func": str.upper},
           "L": {"text": "lower case", "func": str.lower},
           "C": {"text": "Capitalization", "func": lambda x: x}
          }

data = '"The most profound technologies are those that disappear: they weave themselves into fabric of everyday life until are indistinguishable from it" [Mark Weiser, The Computer for the 21st Century, Scientific American, Sept. 1991]'

for c in formats:
    print('Press "{}" and "Enter" for {}.'.format(c, formats[c]['text']))

letter = input("Please type a letter and press enter: ")
if letter in formats:
    print(formats[letter]['func'](data))
