Linux + Python Study Notes

Linux:

Use Vim as a text editor

Vim -- enter vim, press "I" to enter insert (insert text mode), and write the source program

Press ESC and enter ": WQ + source file name" -- save and exit Vim

 

When you enter vim, you can name the source file:

VIM + source file name -- enter Vim

 

RM + filename -- delete an object

 

 

Python:

If python is installed in Linux, enter "Python" in the command line to obtain the Python version information and enter the python mode.

Python functions can be used in Python mode.

 

#! /Usr/bin/Python
# Filename: If. py

number = 23
guess = int(raw_input('Enter an integer : '))

if guess == number:
    print 'Congratulations, you guessed it.' # New block starts here
    print "(but you do not win any prizes!)" # New block ends here
elif guess < number:
    print 'No, it is a little higher than that' # Another block
    # You can do whatever you want in a block ...
else:
    print 'No, it is a little lower than that'
    # you must have guess > number to reach here

print 'Done'
# This last statement is always executed, after the if statement is executed

 

Useraw_input()The function obtains the number that the user guesses.
