making list:
name=[a,b,c]
updating data in the list:
name[0]=10.5 -updating first element of the list
deleting elements from the list:
del(name[1])
copying lists:
areas_copy = list(areas)
areas_copy = areas[:]
Functions:
type() - return type of a value
max() - max value of the list
round(value,rounding precision)
help() - info about function
str() - string
int() - integer
bool() - true or false
float() - float number
len() - lenght of the list, number of elements
sorted(name,reverse=False or True)
Methods:
- for lists:
fam - name of list

sister - string variable
sister.capitalize() - returns first letter capitalized sister value
sister.replace("z","sa") replace "z" with "sa" in sister value
upper() - capitalize all letters
python packages
import math - for exaple
math.pi - use constant pi
from math import pi - importing only one function
numpy - additional feature that provides us possibility to do calculations on list
import numpy as np
np.height = np.array(height) convert list to np array
np.mean
matplotlib for drowing plots
import matplotlib.pyplot as plt
plt.plot(x,y)
plt.scatter(x,y)
plt.show()
