Introduction

word-cloud is a very famous word in natural language processing domain. At first I thought it was just to calculate the frequency of the vocabulary and display the high-frequency words large.

But not only that, the shapes and the styles of characters are all learned not as simple as I thought.

I am a person who likes new things, so I came to study the wordcloud module in Python today and record my experience here.

Introduction

Recently, because I have been studying the interface of the program, I got many strange problems.

I want to record today is how to merge two pictures. I found that if I simply use the composite() function in PIL, the second picture will be overwritten by the first picture. So, I started to try convert the background of the second picture to transparent.

After converting the image to a transparent background, the result of the merging is quite natural to me.

I will start to introduce how to merge two pictures in below.

Introduction

Hello! Today I want to record the “pickle” module in Python. The “pickle” module is very famous module in Python, its usage is like another Python package “Json”, it can compress the data and store it. If we want to load the data we store, we can easily call the “load()” function to restore our session.

Introduction

Whatever programming language we used, we always selected Json format to store our data.

Json (JavaScript Object Notation) is a lightweight data-interchange format, and it is readable and suitable for storing data. But in Python, sometimes we have performance bottlenecks in reading Json files, especially when the files are too large.

When we write Python code, sometimes we want to visualize the ‘progress bar’ to help us understand where our program is currently executing. For this need, instead of writing the progress bar ourselves, we can consider using a well-known progress bar module in Python—tqdm.

Json format file is very easily to process, and many programming language support it. So this data format is quite suitable for joint access to a data and development between different programming languages.

Today I want to introduce how to use the Python package “json” to write and load a Json format file.

At the beginning, I wanted to use the Python package fontTools to solve the problem, but later I found that the Imagefont module in Pillow was better.

The use of map() function in Python is very simple, so simple that it hardly needs any explanation. However, the map() function is still used in many places, so it is still slightly recorded.

If we want to processing date and time using Python, the datetime module that comes to minds first. The datetime module encapsulates Python’s date-related processing very well, and I have used it a lot in crawlers.
