python——进度条配置——tqdm

比眉伴天荒 2023-07-01 07:29 17阅读 0赞

Tqdm 是一个快速，可扩展的Python进度条，可以在 Python 长循环中添加一个进度提示信息，用户只需要封装任意的迭代器 tqdm(iterator)。  
使用pip就可以安装。

使用方法一: tqdm

tqdm(list)方法可以传入任意一种list,比如数组

from tqdm import tqdm
    
    for i in tqdm(range(1000)):  
         #do something
         pass  
     
      
     
      
       1
       2
       3
       4
       5

或者string的数组

for char in tqdm(["a", "b", "c", "d"]):
        #do something
        pass
     
      
     
      
       1
       2
       3

使用方法二: trange

trange(i) 是 tqdm(range(i)) 的简单写法

from tqdm import trange
    for i in trange(100):
        #do something
        pass
     
      
     
      
       1
       2
       3
       4

使用方法三: 手动方法

在for循环外部初始化tqdm,可以打印其他信息

bar = tqdm(["a", "b", "c", "d"])
    for char in pbar:
        pbar.set_description("Processing %s" % char)
     
      
     
      
       1
       2
       3

效果：
