the difference back to top 5.3.1 in Python2 There are two types of string str and UnicodeSTR typeWhen the Python interpreter executes the code that produces the string (for example, s= ' forest '), it requests a new memory address and then encode the ' forest ' to the encoding format specified at the beginning of the file, which is already the result of encode, so s can only decode1 #_ *_coding:gbk_*_2 #!/usr/bin/env python3 4 x= ' forest ' 5 # Print X.encode (' GBK ') #报错6 print x.decode (' GB

Test Case Design Whitepaper--Scenario design methodologyAuthor:vince Source: Http://blog.csdn.net/vincetest I. Introduction to the methodology Today's software is almost always using event triggering to control the process, the event triggered when the scene is formed, and the same event different trigger sequence and processing results to form an event stream. This idea of software design can also be introduced into the software testing, can be more vivid picture of the event triggered when the

Common python formatting output summary and python output summary This article summarizes some simple and basic formats of output formatting. I will not talk about them here. Let's take a look at the details. I. Print strings >>> print "I'm %s" % ("jihite")I'm jihite Ii. Print the integer >>> print "I'm %d years old" % (17)I'm 17 years old 3. Print floating point numbers >>> print "π=%f" % (3.1415926)π=3.141593 4. Print the floating point number (specify the number of decimal points to be retain
