Question

如果在座谈的话,我为什么会做多重任务? 我是否失踪了yn子?

我想这样做:

files = ["file1", "file2", "file3"]

print "
The following files are available: 
"

i = 0
for file in files:
    i = i + 1
    print i, file

choice = int(raw_input("Enter a file number: "))

if choice ==1:
    file = np.genfromtxt(files[0], usecols = (1,2,3), dtype = (float), delimiter =  	 )
    time = np.genfromtxt(files[0], usecols = (0), dtype = (str), delimiter =  	 )

print time

如果说的话,时间在我之外界定,那么,时间并没有改变,而是选择的改变。

Answer 1

两个变量的文档和时间都必须比你的陈述更严格地界定。

注意“时间”,因为它是假日单元的名称。你们应当使用这一名称的改动(例如,时间)。

Answer 2

除<代码>1外,你不使用任何其他选择,如果选择不<代码>1<>>/代码,则照此办理。

choice = int(raw_input("Enter a file number: "))
choice -= 1 # array index is from 0

if choice < 0 or > 2:
    print "Enter correct choice"
    sys.exit()

file = np.genfromtxt(files[choice], usecols = (1,2,3), dtype = (float), delimiter =  	 )
time = np.genfromtxt(files[choice], usecols = (0), dtype = (str), delimiter =  	 )
