Step 2: Convert the tuple to a string To convert the tuple to a string, we can make use of thejoin()method available for strings. Thejoin()method concatenates elements of an iterable object, such as a tuple, with a specified separator. tuple_string=''.join(map(str,my_tuple)) 1. In...
Python >>> ["Pythonista", 7, False, 3.14159] ['Pythonista', 7, False, 3.14159] >>> ("Pythonista", 7, False, 3.14159) ('Pythonista', 7, False, 3.14159) Here, your list and tuple contain objects of different types, including strings, integers, Booleans, and floats. So, your ...
List indexing is zero-based as it is with strings.Consider the following list:>>> a = ['foo', 'bar', 'baz', 'qux', 'quux', 'corge'] The indices for the elements in a are shown below:List IndicesHere is Python code to access some elements of a:>>> a[0] 'foo' >>> a[...
TypeError: '>' not supported between instances of 'int' and 'str' The tuples in the first comparison contain the same data. The values are a string, an integer, a floating-point number, and a tuple. When comparing item by item, Python uses its internal rules for comparing strings, in...
