我使用python的udacity寫在challange此功能：片不是在Python解釋器工作在udacity

example_input="John is connected to Bryant, Debra, Walter.\

Mercedes is connected to Walter, Robin, Bryant.\ 
Mercedes likes to play The Legend of Corgi, Pirates in Java Island, Seahorse Adventures.\ 
Olive is connected to John, Ollie.\ 
Olive likes to play The Legend of Corgi, Starfleet Commander.\ 
Debra is connected to Walter, Levi, Jennie, Robin.\

for x in string_input: 
    if not ((ord(x)>60 and ord(x)<90) or x=="." or (ord(x)>97 and ord(x)<122)): 
    string_input=string_input[:string_input.index(x)]+string_input[string_input.index(x):] 
    network={} 
    before=0 
    string_input2=string_input 
    while y < string_input.count('.')+1: 
     network[y]=string_input2(0:before) 
     string_input2=string_input2(:before-1) 
     before=string_input2.find('.') 
    return network,len(string_input),string_input

當我運行的編輯器提供了一個錯誤消息的代碼說，切片不工作。

Traceback (most recent call last): 
    File "vm_main.py", line 33, in <module> 
    import main 
    File "/tmp/vmuser_igvmlwmdgu/main.py", line 2, in <module> 
    import studentMain 
    File "/tmp/vmuser_igvmlwmdgu/studentMain.py", line 103 
    network[y]=string_input2(0:11) 
          ^
SyntaxError: invalid syntax

有人能告訴我發生了什麼事嗎？

切片標誌使用方括號... –

你，我的朋友，需要看的Python語法。 –

語法切片在Python中的字符串/列表/元組是括號代替括號[:]，而不是(:)即使用。嘗試：

string_input2[0:11]

例如：

>>> my_string = 'StackOverflow' 
>>> my_string[5:9] 
'Over'
