在调用带有 tqdm 进度条的函数之前打印语句会导致在 tddm 之后打印打印语句

Question

When working with tqdm for a project, I've noticed that when I use a print statement just before I call a function that has a tqdm progress bar, the print statement is printed somewhere in between the progress bars.

I've noticed that this behaviour only occurs in ipython notebooks, not when run in terminal.

from tqdm import tqdm

def long_progress():
    for _ in tqdm(range(100)):
        time.sleep(.05)

for i in range(5):
    print("Show parameters of the progress")
    long_progress()

This behaviour doesn't break anything, I'm just really curious why it is happening.

I've also noticed that when I use time.sleep(0.2) before I call tqdm it's resolved, so it seems like some timing issue.

Edit: Changed print statement to reflect my goal more precisely

Answer 1

Define the print statement outside the loop ie

print("Lets start long progress")
for i in range(5):
    long_progress()

This will call the print before the loop execution.
