Sequence problem for tqdm and print

Recently used python Of tqdm When the package , When combined print At the time of statement , Some problems were found

The code is ：

import tqdm
import time

pbar = tqdm.tqdm(total=100)
print("Start")
for _ in range(100):
	time.sleep(0.01)
	pbar.update(1)
pbar.close()
print("End")

The result is ：

print Statements must either be preceded

import tqdm
import time

print("Start") #  In front of 
pbar = tqdm.tqdm(total=100)
# print("Start") 
for _ in range(100):
	time.sleep(0.01)
	pbar.update(1)
pbar.close()
print("End")

Or use it directly trange

import tqdm
import time

print("Start") 
for _ in tqdm.trange(100):
	time.sleep(0.01)
print("End")
