From a pdf file I extract all the text as a string, and convert it into the list by removing all the double white spaces, newlines (two or more), spaces (if two or more) and on every dot (.) .
Now in my list I want if a value of a list consist of only special characters, that value should be excluded.
pdfFileObj = open('Python String.pdf', 'rb')
pdfReader = PyPDF2.PdfFileReader(pdfFileObj)
pageObj = pdfReader.getPage(0)
text=pageObj.extractText()
z =re.split("\n+|[.]|\s{2,}",text)
while("" in z) :
z.remove("")
print(z)My output is
['split()', 'method in Python split a string into a list of strings after breaking the', 'given string by the specified separator', 'Syntax', ':', 'str', 'split(separator, maxsplit)', 'Parameters', ':', 'separator', ':', 'This is a delimiter', ' The string splits at this specified separator', ' If is', 'no', 't provided then any white space is a separator', 'maxsplit', ':', 'It is a number, which tells us to split the string into maximum of provi', 'ded number of times', ' If it is not provided then the default is', '-', '1 that means there', 'is no limit', 'Returns', ':', 'Returns a list of s', 'trings after breaking the given string by the specifie', 'd separator']Here are some values contain only special characters and I want to remove those. Thanks
>Solution :
Use a regular expression that tests if a string contains any letters or numbers.
import re
z = [x for x in z if re.search(r'[a-z\d]', x, flags=re.I)]
