Python Pandas little tips with the Lambda Function

Python Pandas little tips with the Lambda Function

Pandas

Pandas is a useful tool for data science because we can use this tool to analyze, visualize & manipulate data stored within data sets, or in coding terms, within data frames.

Python Lambda

  • A lambda function is a small anonymous function.
  • A lambda function can take any number of arguments, but can only have one expression.
  • Here’s a little tips that we can using lambda to do some easy data process on dataframe:
x = [176, 166, 156, 186] 
df = pd.DataFrame({'height' : x}) 
df['inch'] = df['height'].apply(lambda x: x/2.54) 
df

Convert a shell script into an executable binary

Convert a shell script into an executable binary This article will help you to create binary file of your shell script, so no one can see the source code of your script and we can use them as a command. To create binary file from a script we use SHC compiler written by Francisco Javier Rosales García . Shell Script Compiler (SHC) 1. Download shc and install it $ wget http://www.datsi.fi.upm.es/~frosal/sources/shc-3.8.9.tgz $ tar xvfz shc-3.8.7.tgz $ cd shc-3.8.7 $ make 2. Verify that shc is installed properly. $ ./shc -v shc parse ( -f ) : No source file specified shc Usage: shc [ -e date ] [ -m addr ] [ -i iopt ] [ -x cmnd ] [ -l lopt ] [ -rvDTCAh ] -f script 3. Create a Sample Shell Script $ vi test.sh #!/bin/bash need to put at the beginning of a script file. #!/bin/bash echo -n "Test" 4. Create Binary of Script $ ./shc -T -f test.sh -T : this will allow the created binary files to be traceable using programs like strace...

Understanding htop value

Understanding htop value htop columns meaning Here is a list that explains what each column means. PID: A process’s process ID number. USER: The process’s owner. PRI: The process’s priority. The lower the number, the higher the priority. NI: The nice value of the process, which affects its priority. VIRT: How much virtual memory the process is using. RES: How much physical RAM the process is using, measured in kilobytes. SHR: How much shared memory the process is using. S: The current status of the process (zombied, sleeping, running, uninterruptedly sleeping, or traced). %CPU: The percentage of the processor time used by the process. %MEM: The percentage of physical RAM used by the process. TIME+: How much processor time the process has used. COMMAND: The name of the command that started the process. The difference between VIRT, RES and SHR VIRT stands for the virtual size of a process, which is the sum of memory it is actually using, memory it ...
