python - 收到错误 : list assignment index out of range

Question

我在以下代码中收到超出范围的错误列表分配索引:

n=input("How many numbers?\n")
print "Enter ",n," numbers..."
a=[]
for i in range(0,n):
    a[i]=input()

elem=input("Enter the element to be searched: ")

for i in range(0,n):
    if a[i]==elem:
        flag=1
        break

if flag==1:
    print "Item is present in the list"
else:
    print "Item is not present in the list"

Answer 1

使用 int 添加一些类型安全，使用列表方法 append 和运算符 in:

n = input("How many numbers?\n")
n = int(n)
print "Enter ", n, " numbers..."
a = []
for i in range(n):
    x = input()
    a.append(x)

elem = input("Enter the element to be searched: ")

if elem in a:
    print "Item is present in the list"
else:
    print "Item is not present in the list"
