This is the first step in running something in Python.

Questions to [mailto:davrot@uni-bremen.de David Rotermund]

== These are the same stings ==
<syntaxhighlight lang="python">some_string = "this is a string"
some_string = 'this is a string'</syntaxhighlight><syntaxhighlight lang="python">print(some_string)</syntaxhighlight>Output:<syntaxhighlight lang="python">this is a string</syntaxhighlight>

== These are comments ==
<syntaxhighlight lang="python"># This is comment
a = 1 # This is a comment too! (not the a=1)</syntaxhighlight>

== [https://docs.python.org/3/library/functions.html#print print] ==
<syntaxhighlight lang="python">print(*objects, sep=' ', end='\n', file=None, flush=False)</syntaxhighlight><blockquote>Print objects to the text stream file, separated by sep and followed by end. sep, end, file, and flush, if present, must be given as keyword arguments.

All non-keyword arguments are converted to strings like str() does and written to the stream, separated by sep and followed by end. Both sep and end must be strings; they can also be None, which means to use the default values. If no objects are given, print() will just write end.

The file argument must be an object with a write(string) method; if it is not present or None, sys.stdout will be used. Since printed arguments are converted to text strings, print() cannot be used with binary mode file objects. For these, use file.write(…) instead.

Output buffering is usually determined by file. However, if flush is true, the stream is forcibly flushed.</blockquote>

=== Help for a function ===
Here the function round() as an example. Please note that () is missing with the help function:<syntaxhighlight lang="python">help(round)</syntaxhighlight><syntaxhighlight lang="python">Help on built-in function round in module builtins:

round(number, ndigits=None)
Round a number to a given precision in decimal digits.

The return value is an integer if ndigits is omitted or None. Otherwise
the return value has the same type as the number. ndigits may be negative.</syntaxhighlight>

=== Help for a keyword ===
Keywords are build-in core instructions.<syntaxhighlight lang="python">help("for")</syntaxhighlight><syntaxhighlight lang="python">The "for" statement
*******************

The "for" statement is used to iterate over the elements of a sequence
(such as a string, tuple or list) or other iterable object:

for_stmt ::= "for" target_list "in" expression_list ":" suite
["else" ":" suite]

The expression list is evaluated once; it should yield an iterable
object. An iterator is created for the result of the

print(keyword.kwlist)
print(keyword.softkwlist)</syntaxhighlight><syntaxhighlight lang="python">['False', 'None', 'True', 'and', 'as', 'assert', 'async', 'await', 'break', 'class', 'continue', 'def', 'del', 'elif', 'else', 'except', 'finally', 'for', 'from', 'global', 'if', 'import', 'in', 'is', 'lambda', 'nonlocal', 'not', 'or', 'pass', 'raise', 'return', 'try', 'while', 'with', 'yield']
