How to read entire text file in Python?

Often one might need to read the entire content of a text file (or flat file) at once in python. In this post, we showed an example of reading the whole file and reading a text file line by line. Here is another way to import the entire content of a text file.

<h1>Open a file: file</h1>

file = open(&#039;my_text_file&#039;,mode=&#039;r&#039;)

<h1>read all lines at once</h1>

all_of_it = file.read()

<h1>close the file</h1>

file.close()
