calculates the number of bytes>>> Len (b ' ABC ') 3>>> len (b ' \xe4\xb8\xad\xe6\x96\x87 ') 6>>> len (' Chinese ' encode (' Utf-8 ')) 61 Chinese characters are UTF-8 encoded and typically consume 3 bytes, while 1 English characters take up only 1 bytes.We often encounter str and convert to and bytes from each other when manipulating strings. In order to avoid garbled problems, we should always adhere to the use of UTF-8 encoding str and bytes conversion.The

This article mainly introduces common Python string formatting methods, and analyzes the usage tips of the percent sign method and the format function for string formatting in the form of examples, for more information about how to format strings in Python, see the following example. We will share this with you for you

example can further illustrate that an int contains 4 bytes, and a byte is a form of \x14. >>> a=20>>> b=400>>> t=struct.pack (' II ', A, b) >>> T ' \x14\x00\x00\x00\x90\x01\x00 \x00 ' >>> len (t) 8>>> type (a) 3, the introduction of the structA=20,b=400struct There are three methods, the Pack (Fmt,val) method is to convert the Val data in the format of FMT to binary data, T=struct.pack (' II ', A, b), convert a, B to binary form ' \x14\x00\ X00\x00\

The Python string is formatted with the character% format 1 format 2 character% (variable 1, variable 2), and the% format represents the type that accepts the variable. Examples of simple uses are as follows: # Example: String formatting Name = ' 17jo 'print ' www.%s.com '%name>> www.17jo.com Name = ' 17jo 'Zone = '

Python has two modules, time and DateTime, which, of course, need to be import first when used.Get system Current Time Time.localtime (Time.time ())The formatted output of the time can be used with the strftime, called Time.strftime ()Example for Current_time=time.strftime ('%y-%m-%d ', Time.localtime (Time.time ()))The time format for the output is 2015-02-11, and this output is a string type of dataand da

Python standard library: built-in Function format (value [, format_spec]) This function formats the value in the format of format_spec. However, the function explains that format_spec is determined by the value type. Different types have different formatting interpretations. When the format_spec parameter is null, this function is equivalent to the str (value) fu
