Reading user input from the keyboard is a valuable skill for a Python programmer, and you can create interactive and advanced programs that run on the terminal. In this tutorial, you'll learn how to create robust user input programs, integrating error ha
On reading the Enter key, the program proceeds to the next statement. Let use change our program to store the user input in name and city variables.#! /usr/bin/python3.11 name = input() city = input() print ("Hello My name is", name) print ("I am from ", city) ...
Read a string from standard input. The trailing newline is stripped. The prompt string, if given, is printed to standard output without a trailing newline before reading input. If the user hits EOF (*nix: Ctrl-D, Windows: Ctrl-Z+Return), raise EOFError. On *nix systems, readline is ...
2.读取文本文件(readtext.py) 程序如下: #read and dislay text file print("read and dislay text file") fname = input("Enter filename:") print #display a empty line #attempt to open file for reading try: fobj = open(fname, 'r') except IOError: print("file open error:") else: #...

'r'(reading)是默认访问模式,除此之外,open()函数还有很多种其他文件访问模式,这里只介绍对网工来说最常用的几种模式: open()函数的上述6种模式必须熟练掌握,关于它们的具体使用将在下文中举例讲解。 3.3.2 文件读取 在使用open()函数创建了文件对象之后,我们并不能马上读取文件里的内容。如下例所示,在创建了...
