print() with end=

What you will learn

By the end of this lesson, you'll understand:

• What is Syntax-6: print(value, end="Delimiter")?
• Why does print() normally move to the next line?
• How do you display values horizontally on the same line?

What is end=?

By default, every print() statement ends with a newline (\n), so the next output starts on the next line.

The end= parameter replaces the newline with any delimiter you choose.

print(value, end="Delimiter")

Key idea: instead of moving to the next line, Python prints the delimiter and continues on the same line.

Default behavior of print() (PrintDefaultEx.py)

# PrintDefaultEx.py
for val in range(10, 13):
    print(val)

10
11
12

Each call to print() automatically moves the cursor to the next line.

Syntax-6: space delimiter (PrintEndSpaceEx.py)

Use a space to print values horizontally. This is the first example from your Display Result notes.

# PrintEndSpaceEx.py
for val in range(10, 16):
    print(val, end=" ")

10 11 12 13 14 15

The space becomes the separator between each value.

Arrow delimiter (PrintEndArrowEx.py)

You can use any string as the delimiter.

# PrintEndArrowEx.py
for val in range(10, 16):
    print(val, end="-->")

10-->11-->12-->13-->14-->15-->

This is useful when displaying sequences or process flows.

Comma delimiter (PrintEndCommaEx.py)

# PrintEndCommaEx.py
for val in range(10, 16):
    print(val, end=",")

10,11,12,13,14,15,

The comma replaces the newline after every value.

Understanding range(10, 16)

Your notes use range(10, 16). It generates:

Rule: range(start, stop) includes the start value but excludes the stop value.

Expression	Output
range(1, 5)	1, 2, 3, 4
range(10, 16)	10, 11, 12, 13, 14, 15

Default vs end=

Code	Result
print(val)	Each value appears on a new line
print(val, end=" ")	Values stay on the same line with spaces
print(val, end="-->")	Values separated by arrows
print(val, end=",")	Values separated by commas

Real-world examples

Roll numbers (PrintEndRollEx.py)

# PrintEndRollEx.py
for roll in range(101, 106):
    print(roll, end=" ")

101 102 103 104 105

Process steps (PrintEndStepsEx.py)

# PrintEndStepsEx.py
steps = ["Start", "Load", "Process", "Finish"]
for step in steps:
    print(step, end=" -> ")

Start -> Load -> Process -> Finish ->

CSV-style output (PrintEndCsvEx.py)

# PrintEndCsvEx.py
marks = [85, 92, 78, 88]
for mark in marks:
    print(mark, end=",")

85,92,78,88,

This is similar to comma-separated values (CSV).

Why use end=?

Without end=, creating horizontal output requires more work.

Without end= (PrintNoEndEx.py):

# PrintNoEndEx.py
print(1)
print(2)
print(3)

1
2
3

With end= (PrintWithEndEx.py):

# PrintWithEndEx.py
print(1, end=" ")
print(2, end=" ")
print(3)

1 2 3

The final print(3) uses the default newline, ending the line neatly.

Key terms

Term	Meaning
end=	Replaces the default newline character
Delimiter	The string printed after each value
Horizontal output	Output displayed on the same line
Newline (\n)	Default ending used by print()
range()	Generates a sequence of numbers

Summary

• By default, print() ends with a newline
• end="..." replaces that newline with any delimiter
• end=" " prints values horizontally with spaces (PrintEndSpaceEx.py)
• end="-->" creates arrow-separated output (PrintEndArrowEx.py)
• range(10, 16) produces 10 to 15, because the stop value is excluded

Quick knowledge check

1. What does end= replace?
   The default newline.

2. What is the output of print(5, end=" ") followed by print(6)?
   5 6

3. What delimiter creates arrow-separated output?
   end="-->"

4. Does range(10, 16) include 16?
   No, it stops at 15.
