Generating a new date column from the month, day and year columns in data table using Python Pandas.

When working on datasets, sometimes we have situation where year, month and day part of a date variable are stored separately as integers in three different columns instead of a single properly formatted column with date values. To work on the dates in that case, we’ll need to create a new date column from the three columns. To do so we first need to copy three columns into a new data frame (df2) using copy function nd then use to_datetime function to generate new column containing dates.

Copy year, month and day columns to new data frame.

df2 = df[[‘view_year’,’view_month’,’view_day’]].copy()

Change column names to “year”, “month” and “day”.

df2.columns = [“year”, “month”, “day”]

Use to_date time function to create required date column.

df[‘new_date’]=pd.to_datetime(df2 , errors=’coerce’)

Complex numbers, Argand and Euler planes

Complex numbers are numbers that consist of a real part and an imaginary part. They can be written in the form a + bi, where a and b are real numbers and i is the imaginary unit, which is defined as the square root of -1.

The real part of a complex number is denoted by Re(z) and the imaginary part by Im(z). The magnitude or absolute value of a complex number z is denoted by |z| and is equal to the distance from the origin to the point representing z in the complex plane.

The complex plane is a graphical representation of the set of complex numbers, where the real part of a complex number is plotted on the x-axis and the imaginary part is plotted on the y-axis. This allows us to visualize complex numbers as points in a two-dimensional space.

There are two commonly used systems for representing complex numbers graphically: the Argand plane and the Euler plane.

The Argand plane, named after the French mathematician Jean-Robert Argand, is a graphical representation of the complex plane where the x-axis represents the real part of a complex number and the y-axis represents the imaginary part. In the Argand plane, complex numbers are represented by points, and the magnitude and direction of a complex number can be easily visualized.

The Euler plane, named after the Swiss mathematician Leonhard Euler, is a modified version of the Argand plane, where the real and imaginary axes are rotated by an angle of 45 degrees. In the Euler plane, the x-axis represents the real part plus the imaginary part divided by the square root of 2, and the y-axis represents the imaginary part minus the real part divided by the square root of 2. The advantage of the Euler plane is that the multiplication of complex numbers corresponds to adding their angles in the plane, making it useful in certain applications, such as signal processing.

Given below is the Python script to create plots for the Argand and Euler planes using Python’s Matplotlib library.

import matplotlib.pyplot as plt
import numpy as np

# Create data for a complex number z = 3 + i
z = 3 + 1j

# Create data for the Argand plane
argand_x = [0, z.real]
argand_y = [0, z.imag]

# Create data for the Euler plane
euler_x = [0, z.real + z.imag / np.sqrt(2)]
euler_y = [0, z.imag - z.real / np.sqrt(2)]

# Create the plots
fig, (ax1, ax2) = plt.subplots(1, 2, figsize=(14,5))


ax1.plot(argand_x, argand_y, 'bo-')
ax1.set_xlabel('Real')
ax1.set_ylabel('Imaginary')
ax1.set_xlim([-4, 4])
ax1.set_ylim([-4, 4])
ax1.grid(True)

ax2.plot(euler_x, euler_y, 'ro-')
ax2.set_xlabel('Real + Imaginary / sqrt(2)')
ax2.set_ylabel('Imaginary - Real / sqrt(2)')
ax2.set_xlim([-4, 4])
ax2.set_ylim([-4, 4])
ax2.grid(True)

plt.show()

Python Program to Print powers from 1 to 5 of numbers from 1 to 20

This program uses nested for loop to print powers of numbers from one to twenty. This program is a simple example of using nested loops in Python to perform a repetitive task, in this case computing and printing the values of number powers from 1 to 5 of numbers from1 to 20. Outer for loop iterate over numbers from 1 to 20 by using range function. Inner loop iterate over powers the number is being raised to, i.e. from 1 to 5.

Python Code:

for i in range(1,21):
  for j in range(1,6):
    print(str(i)+"^"+str(j)+"="+str(i**j))

This code uses nested for loops to compute and print the values of i raised to the power of j for all values of i from 1 to 20 and all values of j from 1 to 5.

The first for loop sets up a loop that will iterate through the values of i from 1 to 20, inclusive. This is done using the range() function, which creates a sequence of numbers from the starting value (1) to the ending value (20) with a step size of 1.
The second for loop is nested inside the first for loop, and sets up a loop that will iterate through the values of j from 1 to 5, inclusive. This is also done using the range() function.
Inside the nested loops, the print() function is called, which will print the result of raising i to the power of j. The str() function is used to convert the integer values of i and j to strings so that they can be concatenated with the other strings. The + operator is used to concatenate the strings together, and the ** operator is used to raise i to the power of j.
The output of each iteration of the nested loops is printed to the console as a separate line. Each line of output represents the value of i raised to the power of j for a particular combination of i and j.
