通过用户输入数字计算阶乘

获取用户输入的数字

num = int(input("请输入一个数字: "))
fac = 1

查看数字是负数，0 或 正数

if num < 0:
print(“抱歉，负数没有阶乘”)
elif num == 0:
print(“0 的阶乘为 1”)
else:
for i in range(1,num + 1):
fac = fac*i
print("%d 的阶乘为 %d" %(num,fac))

外层for循环代表打印9行

for i in range(1, 10):
# 内层for循环打印列
# 第一行1列，第而行2列，以此类推
for j in range(1, i+1):
# 格式化 输出{行}x{列}={行乘列}
print("{}x{}={} “.format(j, i, i*j), end=”")
print()

用open函数，创建一个输出文件:
os.mkdir（“test.txt”）
然后用打开文件方法w+ :
f = open(test.txt,‘w+’)
在f.write(字符串+’ \n’)

f = open(‘log.txt’,‘w’)
print(‘日志文件’,file=f) #print到文件
只要你把log.txt的路径写对就可以print到文件了

a = input(“请输入:”)
f = open(joinPath(‘log.txt’),‘w’)
print(‘把我在命令行输入的输出到txt:’+a,file=f) #print到文件

输出的时候将print换成写入文件方式

fout = open(“a.txt”, “w+”, encoding=“utf-8”)
fout.write(“this string will be output in txt.”)

把结果赋值给变量 content
f = open(“text.txt”,‘wb’)
f.write(content)
f.close()
或者将结果输出，在运行时 python test.py >./test.txt 重定向输出结果。
