>>> A = 123
>>> B = 1.23
>>> type (a)
>>> type (b)
>>> type (str (a))
>>> type (str (b))
Description: First define integers and floating-point numbers, then look at the type, and use the STR () function to turn the object into a string.
The type () function is used here to view the object type. This type () in later learning is very used, just started learning, often because the object type is wrong, causing the program to run an error, then you can use it to
When creating a Web project in Eclipse, although there is an XML build, but add the servlet class file is always not see the update Web. XML, so unusually depressed!On the Internet to check, the original when we create a Web project, we will pop up a dialog box,"Dynamic Web Module Version" This option defaults to 3.0, according to the old specification, should be in Eclipse's webcontent \ Web-inf \ Directory to create Web. Xml.The new specification can be used without web. XML, such as Tomcat 7.

xserver 1.5.x. Let's talk about it in 1.5.3.As mentioned before about the relationship between kdrive and xserver, kdrive is a type of xserver. xserver has several implementations in the Xorg code tree, but the general code is shared.For example, the basic event processing and clip code are all shared. The HW directory contains different xserver implementations. Xorg is only one of them. As mentioned above, kdrive and Xorg have manyThe code is shared

Eth0 indicates the first network card. HWaddr indicates the physical address of the network card. You can see that the physical address (MAC address) of this network card is 00: 0C: 29: D8: 45: 30. The MAC address is determined by the manufacturer. Each network card has a unique address. However, you can manually change the MAC address of the NIC by adding the following to the/etc/rc. d/init. d/network file:
Ifconfig eth0 hw ether
: "device switching requires joint debugging with the driver. For example, if the current earpiece id is 10, you can use amixer of ALSA to set the Enable and disable of earpiece and the size. The value of id must be provided by the driving colleagues ." However, it cannot be confirmed. No script file is found to save these values.

Generator Introduction Basic ConceptsThe generator function has several angles of understanding. Syntactically, it can be understood first that the generator function is a state machine that encapsulates multiple internal states.Executing the Generator function returns a Walker object, that is, the generator function, in addition to the state machine, is a Walker object generation function. Returns the iterator object that iterates through each state within the generator function.Formally, the g

If you want to fix the IP address of the network interface, there are currently three methods: one is to modify the IP address through each release and version-specific tool, and the other is to modify the configuration file of the network interface directly, and the third is to modify the specific file and add the ifconfig instruction to specify the IP address of the NIC. For example, in Redhat or Fedora, the name of the I
