Question

我帮助创建了一段压缩用户输入的代码。然后代码将此压缩版本传输到文件中。代码还将输入发送到文件中以查看文件已压缩了多少。

import gzip, time

plaintext = input("Please enter the text you want to compress: ")
file_ = open('text.txt', 'w')
file_.write(str(plaintext))
file_.close()
with gzip.open('compressed_file.text' + ".gz", "wb") as outfile:
    outfile.write(bytes(plaintext, 'UTF-8'))


with open("data.txt","wb") as fh:
    with open('compressed_file.text.gz', 'rb') as fd:
        fh.write(fd.read())

我想要一些关于如何解压缩文件以进行原始用户输入的帮助。

Answer 1

我认为，只需阅读GZIP文件并写回文件就可以帮到你。


            if (KEY_STATUS.left) {
                this.x -= this.speed;
                if (this.x <= 0) // Keep player within the screen
                    this.x = 0;
            }
            else if (KEY_STATUS.right) {
                this.x += this.speed;
                if (this.x >= this.canvasWidth - this.width) this.x = this.canvasWidth - this.width;
            }

            if (KEY_STATUS.up) {
                console.log(this.y);
                this.y -= this.speed;
                if (this.y < 0) this.y = 0;
                //                if (this.y <= this.canvasHeight / 4 * 3) this.y = this.canvasHeight / 4 * 3;
            }
            else if (KEY_STATUS.down) {
                this.y += this.speed;
                if (this.y >= this.canvasHeight - this.height) this.y = this.canvasHeight - this.height;
                console.log(this.canvasHeight);
                console.log(this.height);
            }
            if (KEY_STATUS.shift) {
                this.speed += 2;
            }
            else if (KEY_STATUS.ctrl) {
                if (this.speed > 2) {
                    this.speed -= 2;
                }
                else {
                    this.speed = 2;
                }
            }

输出

import gzip

plaintext = input("Please enter the text you want to compress: ")

with open("text.txt","wb") as file_:
    file_.write(str(plaintext.encode('utf-8')))

filename = input("Please enter the desired filename: ")
print("Name of file to be zipped is text.txt")
print("Name of GZIP file is ",filename+'.gz')
print("Zipping file...")
with gzip.GzipFile(filename + ".gz", "wb") as outfile:
    outfile.write(open("text.txt").read())

print("Name of unzipped file is unzip_text.txt")
print("Unzipping ...")
with gzip.GzipFile(filename + ".gz", 'rb') as inF:
    with file("unzip_text.txt", 'wb') as outF:
        s = inF.read()
        outF.write(s.encode('utf-8'))

print("Content of unzip file is...")
with open("unzip_text.txt") as fd:
    for line in fd.readlines():
        print line

Answer 2

这是我在另一个问题上找到的答案。

plaintext = input('Please enter some text')
filename = 'foo.gz'
with gzip.open(filename, 'wb') as outfile:
    outfile.write(bytes(plaintext, 'UTF-8'))
with gzip.open(filename, 'r') as infile:
    outfile_content = infile.read().decode('UTF-8')
print(outfile_content)

这会压缩输入，将其存储在文件中，并解压缩文件以进行原始输入。然后将此解压缩的输入打印到shell。
