- 編寫?個函數(shù)褐澎，求1+2+3+...+N
def yxk_sum1(n):
sum1 = 0
for x in range(1,n+1):
sum1 += x
print(sum1)
- 編寫?個函數(shù)籽孙，求多個數(shù)中的最?值
def max1(num1):
import random
list1 = []
for _ in range(0,num1):
item = random.randint(0,1000000000000000000000)
list1.append(item)
print(list1) #打印出所有的值
print(max(list1))
- 編寫?個函數(shù)烈评，實現(xiàn)搖??的功能，打印n個??的點數(shù)和
def sum1(n):
import random
list1 = []
for _ in range(0,n):
item = random.randint(1,6)
list1.append(item)
print(list1) #打印出所有搖色子后的點數(shù)
print(sum(list1))
- 編寫?個函數(shù)犯建，交換指定字典的key和value础倍。
例如:{'a':1, 'b':2, 'c':3} ---> {1:'a', 2:'b', 3:'c'}
def exc():
dict1 = {'a':1,'b':2,'c':3}
list1 = list(dict1.keys())
list2 = list(dict1.values())
list3 = []
for index in range(len(list1)):
list4 = []
list4.append(list2[index])
list4.append(list1[index])
list3.append(list4)
print(dict(list3))
- 編寫?個函數(shù)，三個數(shù)中的最?值
def max1(num1,num2,num3):
print(max(num1,num2,num3))
- 編寫?個函數(shù)胎挎，提取指定字符串中的所有的字?沟启，然后拼接在?起后打印出來
例如：'12a&bc12d--' ---> 打印'abcd'
def find_zi_mu():
str1 = '1u2h3u1h23iu1h2iu3'
str2 = ''
for index in range(0,len(str1)):
str3 = str1[index]
if str3.isalpha():
str2 += str3
print(str2)
- 寫?個函數(shù)，求多個數(shù)的平均值
def ave1(n):
import random
list1 =[]
for _ in range(0,n):
num1 = random.randint(0,500)
list1.append(num1)
print(list1)
print((sum(list1))/n)
- 寫?個函數(shù)犹菇，默認求10的階層德迹，也可以求其他數(shù)的階層
def jiecheng(n):
num2 = 1
for num1 in range(1,n+1):
num2 *= num1
print(num2)
- 寫?個函數(shù)，可以對多個數(shù)進?不同的運算
def yunsuan(n):
import random
num2 = 0
for _ in range(0,n):
num1 = random.randint(0,500)
num2 *= num1
print(num2)
