Output statement in python

• What is the output statement?
  Printing the data to the console is known as the output statement.
• Python Output statement prints any statement to the output window.
• If you want to print some data to console then we can use the print() function in python.
• Python print statement is more flexible than in other programming languages.
• There are various forms for the print statement which are as follows

Form 1

• Python print statement without any argument.
• Print Syntax
  Print()
• This is used to print the blank line.
• If you want line separator we use print statement.
• Python print example
  Print() => this will print blank line.

Form 2

• Python Print statement with the string argument.
• Print Syntax
  Print(string)
  Where string is an argument with string type
• Python print string
  Print(“Python”) => this will print string python
• We can use escape character also
  Example
  Print(“python \n programming “) => this will print python in one line and programming in the new line.

What is the escape character?

• We can use + operator and * operator in print statement.
• + operator in print statement
  + operator is used for string concatenation
  We allow using + (concatenation) operator in between string.
  Whenever we use + both arguments should be str type.
  Example
  Print(“python”+”programming “)
  => this will print pythonprogramming
  When we use + in between string, then both strings are concatenated.
• *operator in print statement
  We can use the * operator in print statement.
  Example
  Print(“python “*2)
  This will printpythonpythonpython
  Whenever we use* operator one argument should be str and others should be interested.
  The * operator will print string the number of times we mentioned.
• We can take multiple arguments in the print statement.
  Example
  Print(“python”+”programming “) =>pythonprogramming.
• Whenever we use+ operator for multiple argument printing then + in between both arguments there will not be space added.
• To print space between argument use, (comma)
  Example
  Print(“python”, “programming “)
• Whenever we use, operator while printing multiple arguments then there will be space get added in between both arguments.

Form 3

• Python Print statement with the variable number of arguments.
• We can use any number of arguments in print function.
• Example
  A, B, C=10, 20,30
  Print(“the values are=”, A, B, C) =>the values are= 10 20 30
• By default, while printing, the default separator is space.
• If you want different separator instead of space, you can do this using the sep attribute.
• September attribute is the separator attribute.
• You can add separator attribute in print function.
• Syntax
  Print(values, sep=”sep attribute “)
• Python print with the separator
  
  sep in python

  Python

  print("Print with sep attribute") A=10 B=20 C=30 print(A,B,C,sep=":")

  1 2 3 4 5

  print("Print with sep attribute") A=10 B=20 C=30 print(A,B,C,sep=":")

  
  Output:-      

  

• Print statement with end attribute
  By default in python print() added at a new line.
  Example
  
  python print

  Python

  print("python") print("programming")

  1 2	print("python") print("programming")

• Output:-  

  

  See in above example print() by default adds a new line for each line.

• Now if you don’t want to print a new line, then use end attribute.
• End attribute Syntax
  Print(values, end=” end attribute “)
• Python print without newline
  
  python print without newline

  Python

  print("python",end=" ") print("programming")

  1 2	print("python",end=" ") print("programming")

• Output:-

  

   

• Note:- Separator attribute is for the separator in between arguments and end attribute for separator at the end.
• Python print example
• print python

  Python

  print("print with seperator : an d end attribute") print(10, 20,30,sep=",", end="......") print(90, 100,sep=":")

  1 2 3

  print("print with seperator : an d end attribute") print(10, 20,30,sep=",", end="......") print(90, 100,sep=":")

• Output:-   

  

Form 4

• Print statement to print object.
• You can pass any object to print statement.
• Syntax
  Print(object)
  Where object can be the list or set or any object.
• Example
  
  print object

  Python

  print("print object") list=[10,20,30] print(list)

  1 2 3

  print("print object") list=[10,20,30] print(list)

• Output:- 

  

Form 5

• Print statement with formatted string.
• Formatted strings are
  %iand%d=>int type
  %f => float type
  %s =>string type
• How can use formatted strings
  Syntax
  Print(“formatted string” %(variables))
  Where there is a space between the formatted string in double quote and %variablelist.
• Example print formatted string python
  A=10
  Print(“value of A is%i” %A) => value of A is 10
  In the above example in%i the value of A is printed.
• You can print multiple formatted strings in a single print statement.
• Example
  A, B, C = 10,20,30
  Print(“A value is%i and B value is%i and C value is%i” %(A, B, C))
  = A value is 10 and B value is 20 and C value is 30
• You can also print arguments with different formatted string in a single print statement.
  Example
  Name = “python”
  L=[10, 20]
  Print(“Name is%s and given list is%d” %(Name, L))
  = Name is python and given list is [10, 20]
  In the above example, we printed one string type and one list.

Print() function with replacement operator

• Replacement operator is {}
• Syntax
  Print(“formatted string {index}”.format(variable list))
• Where format() contains a list of a variable.
  {Index} is the replacement operator with the index which got replaced with an associated variable.
• Example
  Name = “python”
  Fees = 1000
  Print(“course name={0} and it’s fees ={1}”.format(name, fees))
  In above example, replacement operator are replaced with values of variable Specified in format().
  {0} is replaced by name
  And {1} is replaced by fees
  Result we get is
  Course name=python and it’s fees=1000
• In case, you are not specifying index but default it considers index.
  Example
  Name = “python”
  Fees = 1000
  Print(“course name={} and it’s fees ={}”.format(name, fees))
  In the above example, replacement operator is replaced with values of variable Specified in format().
  {} is replaced by name
  And {} is replaced by fees
  Result we get is
  Course name=python and it’s fees=1000
• If you are not specifying an index in replacement operator {} then the order of the variable list is important.
• Another option is, you can write identifier in {} and format order is not important.
  Example
  Name = “python”
  Fees=1000
  Print(“course name={x} and it’s fees ={y}”.format(y=Name, x=fees))
  In above example, replacement operator are replaced with values of variable Specified in format().
  {x} is replaced by name
  And {y} is replaced by fees
  Result we get is
  Course name=python and it’s fees=1000
