The problem that tqdm cannot display in a single line

1. print() Add to tqdm front

from tqdm import tqdm
import time
print("--------------------test--------------------")
for i in tqdm(range(10000), ncols=100):
    time.sleep(0.01)

You can see that the output string format is incorrect , Seriously affect the beauty . But if the operation in the loop does not take time , There will be no such problem .

from tqdm import tqdm
import time
print("--------------------test--------------------")
for i in tqdm(range(10000), ncols=100):
    time.sleep(0.001)

Solution ：

from tqdm import tqdm
import time
print("--------------------test--------------------")
time.sleep(0.01)
for i in tqdm(range(10000), ncols=100):
    time.sleep(0.01)

Insert a sleep time between the string output and the loop , The effect is good .

2. Nesting uses tqdm

from tqdm import tqdm
import time
print("--------------------test--------------------")
for i in tqdm(range(10000), ncols=100):
    for j in tqdm(range(100), ncols=100):
        time.sleep(0.00001)

Do not use in nesting tqdm, I changed the code because I didn't remove the previous use , Cause this to happen , Make the effect a little explosive .

Other problems will be updated later
