Python |从用户处获取列表作为输入
我们经常会遇到需要从用户那里获取数字/字符串作为输入的情况。在本文中，我们将看到如何从用户那里获得一个列表作为输入。 例:
Input : n = 4, ele = 1 2 3 4
Output : [1, 2, 3, 4]
Input : n = 6, ele = 3 4 1 7 9 6
Output : [3, 4, 1, 7, 9, 6]
代码#1: 基础示例
Python 3
# creating an empty list
lst = []
# number of elements as input
n = int(input("Enter number of elements : "))
# iterating till the range
for i in range(0, n):
ele = int(input())
lst.append(ele) # adding the element
print(lst)
输出:
代码#2: 处理异常
Python 3
# try block to handle the exception
try:
my_list = []
while True:
my_list.append(int(input()))
# if the input is not-integer, just print the list
except:
print(my_list)
输出:
代码#3: 使用地图()
Python 3
# number of elements
n = int(input("Enter number of elements : "))
# Below line read inputs from user using map() function
a = list(map(int,input("\nEnter the numbers : ").strip().split()))[:n]
print("\nList is - ", a)
输出:
代码#4: 列表作为输入
Python 3
lst = [ ]
n = int(input("Enter number of elements : "))
for i in range(0, n):
ele = [input(), int(input())]
lst.append(ele)
print(lst)
输出:
代码#5: 使用列表理解和打字
Python 3
# For list of integers
lst1 = []
# For list of strings/chars
lst2 = []
lst1 = [int(item) for item in input("Enter the list items : ").split()]
lst2 = [item for item in input("Enter the list items : ").split()]
print(lst1)
print(lst2)
输出:
