A new programming problem has been trending recently - write a program to print numbers from one to hundred without using any loops or mentioning numbers in the source. Naturally, I was interested in a solution in Python. I got many brilliant answers on Twitter. But first let me show you ...
numbers = [1, 2, 3, 4, 5] fruits = ['apple', 'banana', 'cherry'] 使用list() 构造函数 可以使用 list() 构造函数将其他可迭代对象(如字符串、元组、集合等)转换为列表。 string_to_list = list("hello") string_to_list ['h', 'e', 'l', 'l', 'o'] tuple_to_list = list((...
numbers = [1, 2, 3, 4, 5]或者，创建一个混合不同类型元素的列表：mixed_bag = [3.14, 'apple', True, [1, 2], {'key': 'value'}]当然，如果你尚未确定具体的元素，也可以创建一个空列表，随后再逐步添加：empty_list = []动态数组性质 列表在Python中扮演着动态数组的角色。这意味着它的容量...
numbers=list(range(1,1000001))# convert number from 1 to 1000000 into a list chatper 4-13: tuple 元组 ,修改元组变量,等于创建一个新的元组 dimensions = (200, 50) print("Original dimensions:") for dimension in dimensions: print(dimension) ...
if number >= lastdigi: #removes all numbers >= last digi numbers.remove(number) break #and prints the rest listnum = len(numbers) #this whole section is to try and print the numbers from the list while listnum >= 0: #and match the example output ...
primes = list(primerange(1, n + 1)) for prime in primes: print(prime) # Example usage N = 50 print_primes(N) In this example, we useprimerangefrom thesympylibrary to generate a list of prime numbers up to N and then print them. ...
In this second example, we will use the map() function to convert the list of floats to integers.int_list = list(map(int, float_list)) print(int_list) # [1, 3, 5]We again got the corresponding integers to the floats in float_list. Great!
[1,2,3] + "world!" TypeError: can only concatenate list (not "str") to list 2.2.4 乘法 >>> 'python' *5 // 序列乘法,序列被重复N次 'pythonpythonpythonpythonpython' None: python内建值,确切含义是“这里什么都没有”。所以,如果想初始化一个长度为10的列表,可以按照下面的列子来实现: ...
