Print format output of Python

Use print to output

1. String
2. Integer
3. Floating Point Number
4. Output and precision control

 
Strhello ='HelloPython' PrintStrhello# Output result: HelloPython# Directly output a string
 

1. format the output integer

PythonPrint also supports parameter formatting, which is similar to C-language printf,

Strhello ="The length of (% s) is % d" %('Hello world',Len('Hello world'))PrintStrhello# Output result: the length of (Hello World) is 11
 

2. Format and output a 16-digit integer

 
Nhex = 0x20# % X --- hex hexadecimal# % D --- decimal# % D --- Oct octal Print "Nhex = % x, ndec = % d, noct = % O" %(Nhex, nhex, nhex) # Output result: nhex = 20, ndec = 32, noct = 40# Print the same number in each integer format
 

3. format the output floating point number (float)

 Import   Math  # Default  Print   "Pi = % F"   %   Math . Pi  # Width = 10, precise = 3, align = left  Print   "Pi = % 10.3f"   %   Math . Pi  # Width = 10, precise = 3, align = rigoal  Print   "Pi = %-10.3f"   %  Math . Pi  # Prefill characters  Print   "Pi = % 06d"   %   Int  (  Math . Pi  )  # Output result  # Pig = 3.141593  # Pig = 3.142  # Pig = 3.142  # Pig = 000003  # Formatting, precision, degree, and 

4. format the output string (string)

# Precise = 3Print "%. 3 S" % ("Jcodeer")# Precise = 4Print "%. * S" % (4,"Jcodeer")# Width = 10, precise = 3Print "% 10.3 S" % ("Jcodeer")# Output result:# Jco# Jcod# Jco# Similar to strings, there are also precision, degree, and.
 

5. List)

L =[1,2,3,4,'Jcodeer']PrintL# Output result: [1, 2, 3, 4, 'jcodeer']# Print the list directly.'''6. Dictionary (dictionary )'''D ={1:'A',2:'B',3:'C',4:'D'}PrintD# Output result: {1: 'A', 2: 'B', 3: 'C', 4: 'D '}# SamePythonIt also supports dictionary output.
 

6. Print automatic line feed

Print automatically adds a carriage return at the end of the row. If you do not need to press enter, you only need to add a comma (,) at the end of the print statement to change its behavior.

 
ForIIn Range(0,5):PrintI,
 

Or directly use the following function for output:

 
Sys.Stdout.Write("Output string")
