2. First error message¶

>>> Print ("hello world!")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'Print' is not defined

Now try it on your own!

If we don’t use quotation marks, the computer will interpret our message as a Python command, generating a syntax error
"hello world" is different from hello world

>>> print (hello world)
  File "<stdin>", line 1
    print (hello world)
                    ^
SyntaxError: invalid syntax

Now try it on your own!

In the Python version we’re using (Python 3), parentheses are not optional when using print()
print("hello world") is different from print "hello world"

>>> print "hello world"
  File "<stdin>", line 1
    print "hello world"
          ^
SyntaxError: missing parenthesis in call to 'print'

Now try it on your own!

Initial spaces have a meaning in Python that we’ll see later on, in this case it generates a syntax error again
These spaces are called indentations

>>>   print("first message!")
  File "<stdin>", line 1
    print "hello world"
  ^
SyntaxError: unexpected indent

Now try it on your own!
