使用python

标签: python-2.7 stringbuffer

我制作了以下脚本,以读取字符串缓冲区并将数字分配到6个不同的变量中。我发现了一个使用switch-case方法在C#中执行相同操作的示例,当我在python中尝试类似的方法时(如下所示),我获得了所需的结果,但是读取缓冲区的时间过多(超过一秒钟) 。该脚本只是测试该方法的一种方式,它将是更大的开环控制代码的一部分,因此循环时间确实很重要。有什么更快的方法可以在python中做吗?我使用python 2.7。先感谢您。

Julio = '123.5,407.4,21.6,9.7,489.2,45.9/\n'

letter = ''
x_c = '' 
y_c = '' 
z_c = '' 
theta_c = '' 
ux_c = '' 
uy_c = '' 
variable_number = 1

def one():
    global x_c
    x_c += letter

def two():
    global y_c
    y_c += letter

def three():
    global z_c
    z_c += letter

def four():
    global theta_c
    theta_c += letter

def five():
    global ux_c
    ux_c += letter

def six():
    global uy_c
    uy_c += letter

def string_reader(variable_number):
    switcher = {
        1: one,
        2: two,
        3: three,
        4: four,
        5: five,
        6: six
    }
    # Get the function from switcher dictionary
    func = switcher.get(variable_number, lambda: 'Invalid variable number')
    # Execute the function
    print func()

for letter in Julio:
    if (letter != '/') and (letter != ',') and (letter != '\n'):
        string_reader(variable_number)
    elif (letter == '/'):
        break
    elif (letter == '\n'):
        break
    else:
        variable_number = variable_number + 1


print x_c, y_c, z_c, theta_c, ux_c, uy_c

Err ...你不是在使事情变得复杂吗?

>>> Julio = '123.5,407.4,21.6,9.7,489.2,45.9/\n'
>>> x_c, y_c, z_c, theta_c, ux_c, uy_c = Julio.strip().rstrip("/").split(",")[:6]
