为什么递归终止后返回的时候,我这个只返回了end2没有返回end1呢?
int score = 100; 2int a = score - 60; 3char level = 'E'; 4while(true){ 5 if(a<0) break; 6 level--; 7 a -= 10; // a = a - 10; 8 if(level=='A') break; // 封顶 9} 10cout << level << endl;
这里的while后面圆括号里为什么写个true
找到了,再最后面,我前面用手机看的所以看不到
服务器文档版的在哪里,。。。。。。。。。。。。。。。。。非要凑够20个字
from flask import Flask,request
app = Flask(__name__)
@app.route('/upload',methods=['post'])
def upload():
jpg = request.files.get('jpg')
with open('./imgs/img1.jpg','wb') as f:
f.write(jpg.read())
return'上传成功!'
if __name__ == '__main__':
app.run(debug=True)
我把return返回的内容放在打开文件写入操作的后面就成功了!为什么?
int a = 5, b = 8; int x = 100; if(a>10 && (x=b)){ cout << "here" << endl; } cout << x << endl;
为什么x=b要打括号,a>10不打括号
能上传成功,但是找不到图片,postman软件的Bulk Edit有“This file isn't in your working directory.Teammates you share this request with won't be able to use this file. To make collaboration easier you can setup your working directory in Settings.”
这是因为什么原因?
a,b是两个月份值,用整除取余求a月到第二年b月有几个月

老师,我直接把我本地的一个项目提交,为什么失败了
从for循环开始细讲一下,没看懂range3、4那里
# BaseConverter的类对象中的regex="[^/]+",但是自定义的时候regex没有以 / 开头。按理说不是应该对齐吗?
qt安装完成过后,注册好了,添加到桌面后就打不开了
