For this - you can use the dir() function.
Example:
num = 89
str = "Dmitri"
bl = False
fl = 3.14
print("int methods:")
print(type(num))
print(dir(num))
print("str methods:")
print(type(str))
print(dir(str))
print("bool methods:")
print(type(bl))
print(dir(bl))
print("float methods:")
print(type(fl))
print(dir(fl))
