前言:
现时看官们对“python 减法”大致比较讲究,朋友们都需要学习一些“python 减法”的相关知识。那么小编在网络上汇集了一些有关“python 减法””的相关文章,希望看官们能喜欢,你们快快来了解一下吧!儿子二年级口算不过关,没办法,只能天天练习...
学习用python3生成随机100以内口算题,运行后可以在当前目录生成一个“口算100.doc”的文件,已排版,直接打开打印即可:
脚本如下:
# -*- coding: utf-8 -*-import randomdef run(): file1 = open('口算100.doc','w',encoding='utf-8') file1.write("口算\n\n") i = 1 while i <= 160: firstnum = random.randint(1,100) secondnum = random.randint(1, 100) pp = random.randint(1,2) if ( pp == 1 ): if ((firstnum + secondnum) < 100): print("{0:6}{1:3}+ {2:3}= |".format("("+str(i)+")",str(firstnum),str(secondnum)),end=" ",file=file1) i+=1 if ( i % 4 == 1 ): file1.write("\n") elif ( pp == 2): if( firstnum > secondnum): print("{0:6}{1:3}- {2:3}= |".format("("+str(i)+")",str(firstnum),str(secondnum)),end=" ",file=file1) i+=1 if ( i % 4 == 1 ): file1.write("\n") else: print("{0:6}{1:3}- {2:3}= |".format("("+str(i)+")",str(secondnum),str(firstnum)),end=" ",file=file1) i+=1 if ( i % 4 == 1 ): file1.write("\n") file1.close()if __name__=="__main__": run()
