Use built-in functions to convert between integers, floating point numbers, and strings,,Use built-in functions to convert between integers, floating point numbers, and strings

The error happens because you are passing strings to datetime,time() which requires integers ,When I run the script, I get this TypeError:,Another option is to use the datetime stamp like so: ,You'll need to split them into subfields, and then convert each of the smaller numeric strings to actual integers, e

16, 59, 55, 51 13.8

17, 01, 01, 06 13.4
Step 2 continued with import matplotlib.pyplot as pl. . .
import matplotlib.pyplot as plt
import csv
from datetime
import time

x = []
y = []

with open('calibrated.csv', 'r') as csvfile:
   plots = csv.reader(csvfile, delimiter = ' ')
for row in plots:
   x.append(time(row[0]))
y.append(float(row[1]))

plt.plot(x, y, marker = 'o', label = 'brightness')
plt.gca().invert_yaxis()
plt.xlabel('time [UT]')
plt.ylabel('brightness [mag, CR]')
plt.legend()
plt.grid()
plt.show()

The error happens because you are passing strings to datetime,time() which requires integers ,Another option is to use the datetime stamp like so: ,To fix this, you need to convert those strings to appropriate values

Example_snippet/controller/utility/_integer.js/ The warning is related to the . . .
The warning is related to the coordinate parameter of blit().Floating point coordinates, would mean that the origin of the Surface is somewhere in between to pixels in the window.That doesn 't make much sense. The coordinates are automatically, implicitly truncated and that is indicated by the warning.
Use either int or round to convert the floating point coordinates to integral numbers:

   win.blit(playerStand, (round(x), round(y)))
