python编程实战1

试验一：

运用strip（）函数，如下：

python = '\n\t python '
print(python)
print(python.lstrip())
print(python.rstrip())
print(python.strip())
print(python)

 

运行结果为：

python 
python 


python
python


python 

 

Process finished with exit code 0

strip()函数并不改变字符串python，另外lstrip()和strip()都会消除换行和制表，空格等字符。

 

 

试验二：

运用str()函数使int类型变成字符串类型：

代码如下：

age = 18
print('My age is '+str(age)+' years old !')

 

 

运行结果为：

My age is 18 years old !


Process finished with exit code 0

age为int类型，运用str()函数使age变成字符串。

 

试验三：

输入import this

运行之后代码为：

In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!

 

Process finished with exit code 0

上述为python之禅。
