Here are a few examples of how to use some of the above specifiers in your strings: Python >>>"%d"%123.123# As an integer'123'>>>"%o"%42# As an octal'52'>>>"%x"%42# As a hex'2a'>>>"%e"%1234567890# In scientific notation'1.234568e+09'>>>"%f"%42# As a floating-point ...
In the first example, you use the function to create an empty string. In the other examples, you get strings consisting of the object’s literals between quotes, which provide user-friendly representations of the objects. At first glance, these results may not seem useful. However, there are...
