Python 读写文件并截取空格之前的自字符串 保存到数组中

def getDeviceServial( self):

print( "获取所有的devices，并返回devices[]")

# 创建一个数组用来存放devices

devices = []

# 将所有的devices 写入devices.text

devicesPath = str(os.getcwd())

os.system( "adb devices > "+devicesPath+ "/a3s/devices.text")

# 读取devices.text

f = open(devicesPath+ "/a3s/devices.text", "r")

content = f.readlines()

i = 1

while i < len(content) and content[i] != "":

            # 这里是获取空格之前的字符串的代码

findNumber = content[i].find( " ")

devices.append(content[i][ 0:findNumber])

i += 1

# 读取所有的devices

for device in devices:

print(device)

return devices
