问题描述

我尝试将输入字符串xyz拆分成3个标记，然后再拆分成3个整数，分别称为x、y和z。 我希望它这样做，这样我就可以进行更少的输入，然后能够将它们用于mc.setblocks(x1, y1, z1, x, y, z, BlockId)的坐标。我如何将它分开，以使它变成3个不同的整数，或者将它们分割成标记来做到这一点？我知道如何在Java中做到这一点，但我不知道如何在Python中做到这一点。它应该如下所示：

xyz1 = input("enter first coordinates example: 102 36 74")
st = StringTokenizer(xyz1)
x = st.nextToken
y = st.nextToken
z = st.nextToken

推荐答案

我试着写这篇文章，这样你就能看到发生了什么：

xyz1 = input("Enter first 3 coordinates (example: 102 36 74): ")

tokens = xyz1.split() # returns a list (ArrayList) of tokenized values
try:
    x = int(tokens[0])   # sets x,y,z to the first three tokens
    y = int(tokens[1])
    z = int(tokens[2])
except IndexError:       # if 0,1,2 are out of bounds
    print("You must enter 3 values")
except ValueError:       # if the entered number was of invalid int format
    print("Invalid integer format")

如果只输入了三个以上的坐标，则应将输入标记化并在其上循环，将每个标记转换为int并将其附加到列表中：

xyz1 = input("Enter first 3 coordinates (example: 102 36 74): ")

tokens = xyz1.split() # returns a list (ArrayList) of tokenized values
coords = []     # initialise empty list
for tkn in tokens:
    try:
        coords.append(int(tkn))     # convert token to int
    except ValueError:       # if the entered number was of invalid int format
        print("Invalid integer format: {}".format(tkn))
        raise
print(coords)   # coords is now a list of integers that were entered

try:
    xyz1 = input("Enter first 3 coordinates (example: 102 36 74): ")
    coords = [int(tkn) for tkn in xyz1.split()]
except ValueError:       # if the entered number was of invalid int format
    print("Invalid integer format: {}".format(tkn))
    raise
