如何在 python 的 CSV 文件中写入逗号分隔值？

Question

with open('value.csv', 'w') as f:
writer = csv.writer(f)


while time < stage1_burn_time:
# Calculate update simulation variables based on current values:
altitude = altitude + (velocity * delta_t)
acceleration = (thrust(altitude, stage1_thrust_sl, stage1_thrust_vac) / mass) - gravity
velocity = velocity + (acceleration * delta_t)
mass = mass - burn_rate * delta_t
time = time + delta_t
writer.writerow(velocity')
writer.writerow('altitude')
writer.writerow('mass')

这是代码的一部分，我想做的是将值记录为 CSV 文件中的一行逗号分隔值，我收到一条错误消息 Error: iterable expected, not float

Answer 1

import csv

with open('values.csv', mode='w') as values_file:
    values_writer = csv.writer(values_file, delimiter=',', quotechar='"', quoting=csv.QUOTE_MINIMAL)

    values_writer.writerow(['velocity1', 'Altitude1', 'Mass1'])
    values_writer.writerow(['velocity2', 'Altitude2', 'Mass2'])
