Python程序在列表中查找最大的数字 _数据结构

给定一个数字列表, 任务是编写一个Python程序来查找给定列表中的最大数字。
例子：

Input : list1 = [10, 20, 4]Output : 20Input : list2 = [20, 10, 20, 4, 100]Output : 100

方法1：按升序对列表进行排序, 并打印列表中的最后一个元素。

# Python program to find largest # number in a list# list of numbers list1 = [ 10 , 20 , 4 , 45 , 99 ]# sorting the list list1.sort()# printing the last element print ( "Largest element is:" , list1[ - 1 ])

输出如下：

Largest element is: 99

【Python程序在列表中查找最大的数字】方法2：使用max()方法

# Python program to find largest # number in a list# list of numbers list1 = [ 10 , 20 , 4 , 45 , 99 ]# printing the maximum element print ( "Largest element is:" , max (list1))

输出如下：

Largest element is: 99

方法3：在用户提供的输入中查找最大列表元素

# Python program to find largest # number in a list# creating empty list list1 = []# asking number of elements to put in list num = int ( input ( "Enter number of elements in list: " ))# iterating till num to append elements in list for i in range ( 1 , num + 1 ): ele = int ( input ( "Enter elements: " )) list1.append(ele)# print maximum element print ( "Largest element is:" , max (list1))

输出如下：

Enter number of elements in list: 4Enter elements: 12Enter elements: 19Enter elements: 1Enter elements: 99Largest element is: 99

方法4：不使用python中的内置函数：

# Python program to find largest # number in a listdef myMax(list1):# Assume first number in list is largest # initially and assign it to variable "max" max = list1[ 0 ]# Now traverse through the list and compare # each number with "max" value. Whichever is # largest assign that value to "max'. for x in list1: if x > max : max = x# after complete traversing the list # return the "max" value return max# Driver code list1 = [ 10 , 20 , 4 , 45 , 99 ] print ( "Largest element is:" , myMax(list1))

输出如下：
