python 5行代码的神奇操作(2)：
1、九九乘法表2
for i in range(1, 10):
for j in range(i, 10):
print(f'{i}x{j}={i*j}',end=' ')
print(" ")
print("
")输出：
1x1=11x2=21x3=31x4=41x5=51x6=61x7=71x8=81x9=9 2x2=42x3=62x4=82x5=102x6=122x7=142x8=162x9=18 3x3=93x4=123x5=153x6=183x7=213x8=243x9=27 4x4=164x5=204x6=244x7=284x8=324x9=36 5x5=255x6=305x7=355x8=405x9=45 6x6=366x7=426x8=486x9=54 7x7=497x8=567x9=63 8x8=648x9=72 9x9=81
2、逆序打印数字
给一个不多于5位的正整数,逆序打印出各位数字,实现思路如下：
def nixu(n):
l = str(n)
l_str = l[::-1]
print("逆序:%s" % ( l_str))
nixu(2020)输出：
逆序:0202
3、生成词云
from wordcloud import WordCloud
import PIL.Image as image
with open('wordcloud.txt') as fp:
text = fp.read()
wordcloud = WordCloud().generate(text)
img = wordcloud.to_image()
img.show()4、快速生成二维码
以百度为例，生成二维码
from MyQR import myqr myqr.run( words='https://www.baidu.com/', colorized=True, save_name='baidu_code.png')
5、实现批量抠图
import os, paddlehub as hub
huseg = hub.Module(name='deeplabv3p_xception65_humanseg') # 加载模型
path = './imgs/' # 文件目录
files = [path + i for i in os.listdir(path)] # 获取文件列表
results = huseg.segmentation(data={'image': files}) # 抠图想了解更多python知识，请观看python基础语法全讲解视频（马哥教育2014版）视频！！
