In python, strings behave as arrays. Square brackets can be used to access elements of the string. character at nth position str='hello world'print(str[0])# hprint(str[1])# eprint(str[2])# lprint(str[20])# IndexError: string index out of range 4. String Length Thelen()function ...
We all know that all the elements in an array or string inPythonare defined by their indices. To access a specific element, you have to mention its index value. But in some cases you may encounter an error called “IndexError string index out of range”. This error is raised when the ...
Python >>> "{3}".format("foo", "bar", "baz") Traceback (most recent call last): ... IndexError: Replacement index 3 out of range for positional args tuple This call to .format() raises an IndexError exception because index 3 is out of range....
val myString = "Hey there!" var item: Char item = myString[0] // item contains 'H' item = myString[9] // item contains '!' item = myString[10] // Error! String index is out of range item = myString[-1] // Error! String index is out of range ...
Retrieve a given field value. Thekeyargument will be either an integer or a string. If it is an integer, it represents the index of the positional argument inargs; if it is a string, then it represents a named argument inkwargs. ...

Consider the below example, where (\) doesn't have special meaning, s='Hi\xHello' Output The output of the above example is: File "main.py", line 1 s='Hi\xHello' ^ SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \xXX escape...
When the index is negative, we retrieve elements from the end of the string. In this case, we print the last and last but one characters. print(s[0:4]) Ranges of characters can be accessed too. This line prints a range of characters starting from the first and ending with the fourth...
Python bytes decode() function is used to convert bytes to string object. Both these functions allow us to specify the error handling scheme to use for encoding/decoding errors. The default is ‘strict’ meaning that encoding errors raise a UnicodeEncodeError. Some other possible values are ‘ign...
title()}!" 'Hello, PYTHONISTA! Welcome to Real Python!' >>> f"{[2**n for n in range(3, 9)]}" '[8, 16, 32, 64, 128, 256]' In the first f-string, you embed a math expression into the replacement field. In the second example, you use the .upper() and .title() ...
