In this article, a simple python script is provided that can be used to search for a specific character in a file.
If you have a file consisting of some information including name, address, email, post, and so on. You want to extract only email addresses present in that file, then use the following script/block of code. Here, this input file is named “employee_info.txt”.
#!/usr/bin/env python value = '' str = 'Email ID:' file = open('employee_info.txt') result = '' for line in file: if '@' in line: #looking for specific character value = line.splitlines() print ("Email ID:", value) file.close()
Save this script with .py extension. Suppose, save it as ‘script.py’. Open a terminal on Ubuntu or command prompt on Windows and type:
$ python script.py
If you want to redirect the output to a file, then type:
$ python script.py > output.txt
tanimoto_similarities.py: A Python script to calculate Tanimoto similarities of multiple compounds using RDKit.
RDKit  is a very nice cheminformatics software. It allows us to perform a wide range of operations on chemical compounds/ ligands. We have provided a Python script to perform fingerprinting using Tanimoto similarity on multiple compounds using RDKit. (more…)
