首先,我有这个功能:
def change_pos(a, b):
temp = a
a = b
b = temp
print 'Done'
我在另一个函数中调用它,但它只是打印“完成”并且什么都不做。我直接写代码:
a = 1
b = 2
temp = a
a = b
b = temp
它工作正常。这里有什么建议吗?其次,这是我的代码
def check_exception(list):
for element in list:
# Take list of numbers
# \s*: Skip space or not (\t\n\r\f\v), \d: Number [0-9]
# ?: Non-capturing version of regular parentheses
first = re.compile("\s*(?:\[)(\d+)\s*(?:,)").findall(element)
last = re.compile("\s*(?:,)(\d+)\s*(?:\])").findall(element)
# Convert string to integer
first_int = map(int, first)
last_int = map(int, last)
# Check and code above works
i = 0
print first_int[i]
change_pos(first_int[i],first_int[i+1])
print first_int[i+1]
print len(first_int)
#print type(first_int[0])
# Sort
# Error: list index out of range at line 47 and more
i = 0
while i < len(first_int):
if first_int[i] > first_int[i+1]:
change_pos(first_int[i], first_int[i+1])
change_pos(last_int[i], last_int[i+1])
i += 1
# Check exception
j = 0
while j < len(last_int):
if last_int[j] < first_int[j+1]:
return false
break
else:
j += 1
continue
return true
我看到:IndexError: list index out of range at conditions after #Error 感谢您的帮助。:)
