python的while分支

1、輸出0到100,50不輸出，60到90是輸出平方

代碼

count=0while count<=49:print("loop",count)count+=1if count==50:pass
count+=1while count>=51 and count<=59:print("loop",count)count+=1while count>=60 and count<=90:print("loop",count*count)count+=1while count>90 and count<=100:print("loop",count)count+=1

運行結果

運行結果是對的，但是程序有些不簡潔

修改后的代碼為

count=0while count<=100:if count==50:passelif count>=60 and count<=90:print("loop",count*count)else:print("loop",count)count+=1        

運行結果
