The next time you evaluate a notebook cell that contains a Fraction instance, it’ll draw a beautiful math formula instead of printing text.Performing Rational Number Arithmetic on FractionsAs mentioned before, you can use fractions in arithmetic expressions consisting of other numeric types. ...
For example, 1 + 2 is an expression that evaluates to the value 3, while number = 1 + 2 is an assignment statement that doesn’t evaluate to a value. Although running the statement number = 1 + 2 doesn’t evaluate to 3, it does assign the value 3 to number. In Python, you ofte...
for_loop_string.py #!/usr/bin/python3 word = "cloud" for let in word: print(let) 我们定义了一个字符串。 通过for循环,我们将单词的字母一一打印到终端。 $ ./for_loop_string.py c l o u d 这是示例的输出。 Python for循环的else for循环具有可选的else语句,该语句在循环完成时执行。
