Write a function that performs a text search in a text file. The function takes the filename and a list of strings as inputs. The list of strings is the patterns to be searched within the text file. A "*" character within the string is a wildcard character, which can stand for unknown characters with any length greater than zero. It returns a dictionary where keys are the patterns in the list of strings being searched, and values are the number of times they occur. Your function should have the following template: def text_search (filename, patterns): """It searches the file filename and returns a dictionary of search result, showing patterns with number of occurrences""" dic = {} # To be completed... return dic

Write a function that performs a text search in a text file. The function takes the filename and
a list of strings as inputs. The list of strings is the patterns to be searched within the text file. A
"*" character within the string is a wildcard character, which can stand for unknown characters
with any length greater than zero. It returns a dictionary where keys are the patterns in the list
of strings being searched, and values are the number of times they occur. Your function should
have the following template:
def text_search (filename, patterns):
"""It searches the file filename and returns a dictionary of search
result, showing patterns with number of occurrences"""
dic = {}
#To be completed...
return dic
For example, suppose a file with filename "File 1.txt" contains the following texts,
Mary is a girl.
They are girls.
Fish has gills.
By calling the following lines of codes,
strings = ["is", "gi*1"]
print (text_search ("File 1.txt", strings))
The following output is obtained:
{'is': 2, 'girl': 2, 'gill': 1}](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1cbaac23-ac85-41b4-a340-68ba227c3863%2F0826da9e-945f-4477-9cb5-ae3fa737a69f%2Fy6lp8b_processed.jpeg&w=3840&q=75)
