Python - Display contents of text file in reverse order
We will display the contents of the text file in reverse order. To do this, we first create a text file amit.txt
with the following contentDisplay the contents of a text file in reverse order by slicing
Example
Now let us read the contents of the above files in reverse order -
# The file to be read with open("amit.txt", "r") as myfile: my_data = myfile.read() # Reversing the data by passing -1 for [start: end: step] rev_data = my_data[::-1] # Displaying the reversed data print("Reversed data = ",rev_data)
Output
Reversed data = !tisisihT
Display the contents of the text file in reverse order through a loop
Example
# Opening the file to read my_data = open('amit.txt','r') # reversing the data for myLine in my_data: l = len(myLine) rev_data = '' while(l>=1): rev_data = rev_data + myLine[l-1] l=l-1 print("Reversed data = ",rev_data) # Displaying the reversed data
Output
Reversed data = !tisisihT
The above is the detailed content of Python - Display contents of text file in reverse order. For more information, please follow other related articles on the PHP Chinese website!

This tutorial demonstrates how to use Python to process the statistical concept of Zipf's law and demonstrates the efficiency of Python's reading and sorting large text files when processing the law. You may be wondering what the term Zipf distribution means. To understand this term, we first need to define Zipf's law. Don't worry, I'll try to simplify the instructions. Zipf's Law Zipf's law simply means: in a large natural language corpus, the most frequently occurring words appear about twice as frequently as the second frequent words, three times as the third frequent words, four times as the fourth frequent words, and so on. Let's look at an example. If you look at the Brown corpus in American English, you will notice that the most frequent word is "th

This tutorial demonstrates creating a custom pipeline data structure in Python 3, leveraging classes and operator overloading for enhanced functionality. The pipeline's flexibility lies in its ability to apply a series of functions to a data set, ge

Serialization and deserialization of Python objects are key aspects of any non-trivial program. If you save something to a Python file, you do object serialization and deserialization if you read the configuration file, or if you respond to an HTTP request. In a sense, serialization and deserialization are the most boring things in the world. Who cares about all these formats and protocols? You want to persist or stream some Python objects and retrieve them in full at a later time. This is a great way to see the world on a conceptual level. However, on a practical level, the serialization scheme, format or protocol you choose may determine the speed, security, freedom of maintenance status, and other aspects of the program

Python's statistics module provides powerful data statistical analysis capabilities to help us quickly understand the overall characteristics of data, such as biostatistics and business analysis. Instead of looking at data points one by one, just look at statistics such as mean or variance to discover trends and features in the original data that may be ignored, and compare large datasets more easily and effectively. This tutorial will explain how to calculate the mean and measure the degree of dispersion of the dataset. Unless otherwise stated, all functions in this module support the calculation of the mean() function instead of simply summing the average. Floating point numbers can also be used. import random import statistics from fracti
