python的乘法口诀表 python的乘法口诀表 用python来写一个脚本,使得这个脚本在运行后自动输出乘法口诀表. pyton的脚本如下: #!/usr/bin/env python #coding:utf-8 """ file: chengfa.py date: 2017-08-24 author:lijian desc: """ for i in range(1,10): for j in range(1,i+1): print &qu
#乘法口诀 for i in range(1,10): for j in range(1,i+1): print ( j,'*',i,'=',j*i,'',' ',end='') print(end='\n') 注意使用的Python环境为 3.* 2 for i in range(1, 10): print " ".join(["%d*%d=%d" % (j, i, i*j) for j in range(1, i+1)])
用Python语言编程,使用双重循环语句输出"九九乘法表". for i in range(1, 10): # 控制行 for j in range(1, i+1): # 控制列 print(j, 'x', i, '=', j*i, sep='', end='\t') # end='\t'相当于每次打印结束不换行,而是在末尾添加\t(tab): # 而sep=''表示每个打印的字符之间用''内的内容衔接,去掉默认带有的空格 print() # 每打印完一行就最最后打印一个空白,相当于屏
思路:第一行:1*1,第二行:1*2.,2*2,第三行:1*3,2*3,3*3-- 最后一行:1*9,2*9,3*9,-9*9,以此类推,可以设2个数:i,j:让 i 从1循环到9,让 j 从1到小于等于i,输出i*j,需要注意的是同行中i*j不能换行,做完一行循环之后必须换行 range(1,10)让i从1循环到9 for i in range(1,10): #打印乘法口诀表 j=1 while (j<=i): print (j*i), #不能用'+'只能用','来使他不换行 j=j+1 pr
for x in range(1,4): for o in range(0,x-1): print('*',end='') pass pass print('*') print('\n')print("正方形")for c in range(1,4): for b in range(2): print('*',end='*') pass print('*') pass print("乘法表") for m in range(1,10): for n in range
# 1*1 = 1 # 1*2 = 2 2*2 = 4 # 1*3 = 3 2*3 = 6 3*3 = 9 i = 1 j = 1 for j in range(1,10): for i in range(1,j +1): print('%s*%s=%s '%(i,j,i*j),end='') # print(j,'*',i,'=',i*j,end = ' ') print('') 记录一下遇到的问题: 1. for i in j:#报错 TypeError: 'int' object is n
