Python: Tips of the Day

Iterating over a dictionary:

print["Input three integers[sides of a triangle]"]
int_num = list[map[int,input[].split[]]]
x,y,z = sorted[int_num]
if x**2+y**2==z**2:
    print['Yes']
else:
    print['No']

Input three integers[sides of a triangle]
 8 6 7
No

Python: Tips of the Day

You can turn a set into an immutable set

This way, you can no longer modify it:

my_set = frozenset[['a', 'b', 'c', 'd']]

my_set.add["a"]

If you do that, an error will be thrown:

AttributeError: 'frozenset' object has no attribute 'add'

In this shot, we will discuss how to generate a right-angled triangle using stars in Python.

We can print a plethora of patterns using python. The basic and only prerequisite for this is a good understanding of how loops work in Python. Here, we will be using simple for loops to generate a right-angled triangle using stars.

Description

A right-angled triangle must have one angle equal to 90 degrees.

To execute this using Python programming, we will use two for loops:

• An outer loop: To handle the number of rows.
• An inner loop: To handle the number of columns.

Code

Let us see the code snippet below to understand it better.

# Number of rows
rows = 5

# Outer loop to handle the rows
for i in range[rows]:
    
    # Inner loop to handle the columns
    for j in range[i + 1]:
        
        # Printing the pattern
        print["*", end=' ']
    
    # Next Line
    print[]

Explanation

• In line 2, we take the input for the number of rows [i.e. the length of the triangle].

• In line 5, we create a for loop to handle the number of rows.

• In line 8, we create a nested for loop [inner loop], to handle the number of columns.

• In line 11, we print the pattern [*]. Any other character could be printed by being in the print statement. The end statement helps us to be on the same line till the loop finishes.

• In line 14, we use print[], to move to the next line.

In this shot, we will discuss how to generate a right-angled triangle using numbers in Python.

We can print a plethora of patterns using Python. The basic and only prerequisite is a good understanding of how loops work in Python. Here, we will be using simple for loops to generate a right-angled triangle using stars and numbers.

Description

A triangle is said to be right-angled if and only if it has one angle equal to 90 degrees.

To execute this using Python programming, we will be using two for loops:

• An outer loop to handle the number of rows.
• An inner loop to handle the number of columns.

Code

Let’s look at the code snippet below to understand it better.

# Number of rows
rows = 5

# Outer loop to handle the rows
for i in range[rows]:
    
    # Inner loop to handle the columns
    for j in range[i + 1]:
        
        # Printing the pattern
        print[j+1, end=' ']
    
    # Next Line
    print[]

Explanation

• In line 2, the input for the number of rows [i.e., length of the triangle] is taken.

• In line 5, we create a for loop to handle the number of rows.

• In line 8, we create a nested for loop [inner loop], to handle the number of columns.

• In line 11, we print the pattern, and we have printed j+1, which results in iteration from 1 [since j + 1] to length of i in each row. i keeps increasing with increasing rows, and so the numbers keep increasing as the line number increases.

• In line 14, we use print[] to move to the next line.

How do you write a right

To print the right-angled triangle in Python, we can take the input from the user for the length of the triangle. As you can see, Input is taken from the user as [x]. As we know that a for loop is used for iterating over a sequence. Then using nested for loop, you can print the right-angled triangle.

How do you print numbers on a right

Example -.

# This is the example of print simple reversed right angle pyramid pattern..

rows = int[input["Enter the number of rows:"]].

k = 2 * rows - 2 # It is used for number of spaces..

for i in range[0, rows]:.

for j in range[0, k]:.

print[end=" "].

k = k - 2 # decrement k value after each iteration..

for j in range[0, i + 1]:.

How do you find the area of a right

Python.

b = 5..

h = 8..

area = [ b * h] / 2..

print["Area of Right Angle Triangle is :"];.

print[area];.

How do you program a triangle in Python?

Programs to print triangles using *, numbers and characters In the first loop, we iterate from i = 0 to i = rows . The second loop runs from j = 0 to i + 1. In each iteration of this loop, we print i + 1 number of * without a new line. Here, the row number gives the number of * required to be printed on that row.
