p121: *题4.1:猜数字游戏.在程序中预设一个0~9之间的整数,让用户通过键盘输入所猜的数,如果大于预设的数,显示“遗憾,太大了!”:小于预设的数,显示“遗憾,太小了!”,如此循环,直至猜中该数,显示“预测N次,你猜中了!”,其中N是用户输入数字的次数. 源代码: from random import*y=5n=1m=Falsewhile(m==False): x=eval(input("请输入您猜想的数字:")) try: if(x>y):
#include<iostream> #include<string> using namespace std; int main() { string first_name; string last_name; char grade; int age; cout << "What is your first name? "; getline(cin,first_name); cout << endl << "Wha
17.1 写一个程序,从文件中读取一组字符串(每行一个),然后让用户键入模式以便进行字符串匹配. 对于每个模式,程序应该说明文件里共有多少字符串匹配成功,分别是哪些字符串. 对于所键入的每个新模式,不应重新读取文件,应该把这些字符串存放在内存里.文件名可以直接写在程序里. use 5.016; use autodie; my $file_name = 'sample.txt'; open my $fh ,'<',$file_name; chomp (my @strings=<$fh>);
6–6. 字符串.创建一个 string.strip()的替代函数:接受一个字符串,去掉它前面和后面的 空格(如果使用 string.*strip()函数那本练习就没有意义了) 'Take a string and remove all leading and trailing whitespace' def newStrip(str): 'delete blanks around a string' _end = len(str) _start = 0 # delete the blanks
