Question

I am a newbie to Python. I am fetching sensor readings and it has too many decimal places (x.xxxxxxxx) I want to limit the reading into 4 decimals places (x.xxxx).

from altimu10v5.lsm6ds33 import LSM6DS33
from altimu10v5.lis3mdl import LIS3MDL
from altimu10v5.lps25h import LPS25H

from time import sleep

lsm6ds33 = LSM6DS33()
lsm6ds33.enable()

lps25h = LPS25H()
lps25h.enable()

lis3mdl = LIS3MDL()
lis3mdl.enable()

while True:

    #print(lsm6ds33.get_accelerometer_raw())
    print("{:.2f}".format.lsm6ds33.get_accelerometer_g_forces())

    sleep(0.4)

When I run this code I get the following error message:

" attribute error : ' builtin_function_or_method' object has no attribute 'lsm6ds33'

Answer 1

尝试：

print("{:.4f}".format(lsm6ds33.get_accelerometer_g_forces()))

参考：Python: str.format()

Limiting sensor reading into 4 decimal
