These two operators can be applied to strings as well. Any of the following characters or character sequences is considered to constitute a line boundary: Here is an example using several different line separators: If consecutive line boundary characters are present in the string, they are assumed to delimit blank lines, which will appear in the result list: If the optional argument is specified and is truthy, then the lines boundaries are retained in the result strings: The bytes object is one of the core built-in types for manipulating binary data. (Desired output: when i put in abc and 1 i want it to print bcd). When a string value is used as an iterable, it is interpreted as a list of the strings individual characters: Thus, the result of ':'.join('corge') is a string consisting of each character in 'corge' separated by ':'.

Caesar ciphers in Python - ALMADJ.US - klarsen.net Bulk update symbol size units from mm to map units in rule-based symbology. A string is inherently a list of characters, hence 'map' will iterate over the string - as second argument - applying the function - the first argument - to each one. As long as you stay in the domain of the common characters, there is little practical difference between ASCII and Unicode. Given a numeric value n, chr(n) returns a string representing the character that corresponds to n: chr() handles Unicode characters as well: With len(), you can check Python string length.

Square brackets can be used to access elements of the string. s.isprintable() returns True if s is empty or all the alphabetic characters it contains are printable. In this, we multiple string thrice, perform the concatenation and selectively slice string to get required result. If you would like to use a more functional approach to iterating over a string (perhaps to transform it somehow), you can split the string into characters, apply a function to each one, then join the resulting list of characters back into a string.

Here is another way to achieve the same thing: It's easier to write a straight function shifttext(text, shift). Not the answer you're looking for? Use enumerate() to get indexes and the values: You can simplify this with a generator expression: But now you'll note that your % 26 won't work; the ASCII codepoints start after 26: You'll need to use the ord('a') value to be able to use a modulus instead; subtracting puts your values in the range 0-25, and you add it again afterwards: but that will only work for lower-case letters; which might be fine, but you can force that by lowercasing the input: If we then move asking for the input out of the function to focus it on doing one job well, this becomes: and using this on the interactive prompt I see: Of course, now punctuation is taken along. bytes() defines a bytes object of the specified , which must be a positive integer. This may be based on just having used C for so long, but I almost always end up using this C-ish method. But I thought I already did that? Even better is marcog's answer using enumerate.
