HomeBackend DevelopmentPython Tutorial为什么python代码有时候在命令行下和Python Shell中执行的结果不一样呢 ?

回复内容:

首先,如上面 @柯豪 的答案所说,Shell的行为并不完全和Python代码一致

>>> for i in range(5):
...     i
... 
0
1
2
3
4
这个例子非常有意思,无人邀请,我来答一下吧。

使用不熟悉的函数和library是危险的。

重要的话说三遍。

首先,先看这个例子,只是把helloworld.cpp 略加改动,题主觉得这个代码应当输出什么结果?
<span class="cp">#include <cstdio></span>
<span class="cp">#include <iostream></span>

<span class="k">using</span> <span class="k">namespace</span> <span class="n">std</span><span class="p">;</span>

<span class="kt">int</span> <span class="nf">main</span><span class="p">()</span>
<span class="p">{</span>
    <span class="n">cout</span><span class="o"><<</span><span class="n">printf</span><span class="p">(</span><span class="s">"asdf"</span><span class="p">)</span><span class="o"><<</span><span class="n">endl</span><span class="p">;</span>
<span class="p">}</span>
为什么python代码有时候在命令行下和Python Shell中执行的结果不一样呢 ?主要是因为这东西变了.
而c库中的标准的输出没改变.

The reasons why Python scripts cannot run on Unix systems include: 1) Insufficient permissions, using chmod xyour_script.py to grant execution permissions; 2) Shebang line is incorrect or missing, you should use #!/usr/bin/envpython; 3) The environment variables are not set properly, and you can print os.environ debugging; 4) Using the wrong Python version, you can specify the version on the Shebang line or the command line; 5) Dependency problems, using virtual environment to isolate dependencies; 6) Syntax errors, using python-mpy_compileyour_script.py to detect.

Using Python arrays is more suitable for processing large amounts of numerical data than lists. 1) Arrays save more memory, 2) Arrays are faster to operate by numerical values, 3) Arrays force type consistency, 4) Arrays are compatible with C arrays, but are not as flexible and convenient as lists.
