JMeter distributed pressure measurement jmeter can be used to do distributed pressure measurement, need to do is: 1. Install the JMeter on the target press and start Jmeter-server2 in the bin directory under the JMeter root directory. Locate the JMeter properties file in the local JMeter bin directory and modify the HOST3 of the remote hosts for the target presses. Startup--Remote boot jmeter running on Linux

Since most of the servers are now Linux systems, in this case, if you want to do jmeter pressure test:

1. Place the prepared script in the Bin directory under target machine JMeter 2. cd into bin directory 3. On the cmd input command line: Jmeter.bat-n-t-l Nhy.jtl-n does not have a graphical interface-T to run which script-L Save the result, followed by the path, the result must be JTL knot Tail 4. View results: Open the graphical interface of JMeter, add an aggregated report, import the generated JTL file Chalse

• Python cannot use the variable name:

[' and ', ' as ', ' assert ', ' Break ', ' class ', ' Continue ', ' Def ', ' del ', ' elif ', ' Else ', ' except ', ' exec ', ' finally ', ' for ', ' From ', ' global ', ' if ', ' Import ', ' on ', ' is ', ' lambda ', ' no ', ' or ', ' pass ', ' print ', ' raise ', ' return ', ' try ', ' while ' with ', ' yield ']

• When defining a string:

If the string contains single quotation marks, the initialization definition can only use double quotation marks if the string contains double quotation marks, when the initialization definition can only use single quotation marks if the string has both double quotes, and single quotation marks, the initialization of the definition with three single quotation marks

• Comments

Use # Comment, pycharm shortcut ctrl+/use three quotation marks for multi-line annotation

• Conditional judgment

The conditions in Python determine that only if Elseps:python is dependent on indentation to differentiate blocks of code, Python does not need to add semicolons at the end of a sentence

• The type of a variable can be obtained directly from the Python console

PS: ctrl+d quickly copy a line of code

• For And while loops

Python is used to confirm the program block using indentation.

Break: End loop immediately, no matter if you loop has completed continue: End this loop, proceed to the next loop using else in for and while, means that after the loop is finished, else later statements are executed: While loop must have a counter, For can be used without the need for:

• String formatting

Use of the%s placeholder: msg = ' Welcome,%s! Today is the placeholder for%s '% (user, today)%s string, which can be applied to all placeholders for the data type%d integer, and must be a placeholder for the integer%f decimal type, which retains 6 bits by default,%.2f retains 2 decimal places, and will self-round if required to print out%, You need to use a percent of 2%round () to retain the decimal number: print (Round (score, 2))

• List

There are no double types in Python, only the common operations of Float,list are as follows:

There is also a concept in Python called a multidimensional array, which can be used to return the length of the array using Len (list):

Use count to calculate the number of the same value in the array:

You can also use in to determine if there is a value in the array:
