Python Learning DAY3 (function input & print)

Input

1 format:

Input ([prompt]) prompt for cue information ctrl + Z end input

2 function functions:

Accepts a standard input data, returns a string type

3 Examples:

　　

Print

1 format:

　　print ([object, ...], *, sep= ', end= ' \ n ', file=sys.stdout) (end default value is carriage return, customizable symbol)

2 function functions:

Output various types of data: String, Integer, floating-point, perceive, and precision control

3 Examples:

• Print (): Output a blank line
• Print (str or number): Direct output of a string or numeric
• Parameter formatted output
  • #%x---hex hex
  • #%d---Dec decimal
  • #%o---Oct octal
  • #%s---String
  • #%f---float floating point
    • Example 1:
    • STR1 = "The value is:"
    • Number1 = 11
    • Print ("%s%d"% (str1,number1)) #输出 "The value is:11"

• • • Example 2:
    • pi=3.1415926
    • Print ("PI =%10.3f"% math.pi) #输出PI = 3.142
    • Print ("PI =%-10.3f"% math.pi) #输出PI = 3.142
    • Example 3:
    • Print ("%.3s"% ("ABCDE")) #输出abc
    • Print ("%.*s"% (4, "ABCDE")) #输出abcd
    • Print ("%10.3s"% ("ABCDE") #输出ABC (total length is 10, character length is not sufficient in front of the blanks)

• • • Example 4: Printing multiple lines
    • Print ("Your Content" ") or print (" Your content ")
    • Example 5: Print plain text with no escape character: print (R ' content ') or print (R ' content ')
    • Print (R ' abc\n ') #直接打印字符串abc \ n
