Once the user presses the Enter key, all characters typed are read and returned as a string:Feb 19, 2010 · From the Python manual. string.find(s, sub[, start[, end]]) Return the lowest index in s where the substring sub is found such that sub is wholly contained in s[start:end]. Return -1 on failure. Defaults for start and end and interpretation of negative values is the same as for slices. And: string.index(s, sub[, start[, end]]) when you write firstname [a:b] it'll return the value of firstname from char a to char b. so when your firstname is "anna" and you'll type firstname [1:3] you'll get 'nn'. in this case minus one is equal to the index of the last character which is 3. so firstname [0:-1] will return "ann". in your case it should be changed to firstname [0].The find () string method is built into Python's standard library. It takes a substring as input and finds its index - that is, the position of the substring inside the string you call the method on. The general syntax for the find () method looks something like this: string_object.find("substring", start_index_number, end_index_number) Let's ...

Splitting is a string operation in which input is a string containing chunks separated by delimiter. We should extract the chunks from the string as a list. Python – Split string. Python – Split string into specific length chunks. Python – Split string by underscore. Python – Split string by space. You can extract a substring from a string by slicing with indices that get your substring as follows: string [start:stop:step] start - The starting index of the substring. stop - The final index of a substring. step - A number specifying the step of the slicing. The default value is 1. Indices can be positive or negative numbers. Basic String Operations. Strings are bits of text. They can be defined as anything between quotes: As you can see, the first thing you learned was printing a simple sentence. This sentence was stored by Python as a string. However, instead of immediately printing strings out, we will explore the various things you can do to them. If you runt his code you shouul see the 'f' value is deleted. In this method, input_str.rsplit (input_str [-1], 1) splits the string at the last occurrence of the last character, resulting in a list of substrings. Then, ''.join () concatenates those substrings back into a single string without the last character.Also called formatted string literals, f-strings are string literals that have an f before the opening quotation mark. They can include Python expressions enclosed in curly braces. Python will replace those expressions with their resulting values. So, this behavior turns f-strings into a string interpolation tool.
