Basic data types:
1, numeral (int)
python3 in: All numbers are int. n = 1123456789
python2 in: less of the median time to call int, n = 12345 digits long called long, n = 1234567890
View all int function (magic): Similarly str list tuple dict bool
Input int In pycharm inside - "Re-click elsewhere -" the keyboard ctrl click int-- "all the magic out int
int-- converted into a digital string, numeric strings which need be
= a "123"
Print (type (a)) # - Output a type
b = int (a)
b = b + 1000
Print (type (b)) # - type of output b
= num "A"
V = int (num, base = 16) # - indicates convert to hexadecimal num default indicates no base is converted to decimal
print (v)
