2. Overall view dir () quick list

temp = "Alex"
t = Type (temp)

t = Type (temp)
Help (Type (t))

4. Mouse click

temp = "Alex"

Temp.upper ()

Mouse on Upper (), ctr+ left button, auto-position to upper function

common features for basic data types:

integer int

N1 = 123
N2 = 456
Print (N1+N2)  
Print (n1.__add__ (n2))

A1 = "Alex"
ret = A1.capitalize ()
Print (ret)

A1 = "Alex"
ret = A1.center (20, ' * ')
Print (ret)

A1 = "Alex is Alph"
ret = A1.count ("a")
Print (ret)

A1 = "Alex is Alph"
ret = A1.count ("Al", 0,10)
Print (ret)

temp = "Hello"
Print (Temp.endswith (' e ', 0,2))

Content = "hello\t999"
Print (content)
Print (Content.expandtabs ())
Print (Content.expandtabs (20))

s = "Alex Hello"
Print (S.find ("ex"))

s = "Hello {0}, Age{1}"
Print (s)
New1 = S.format (' Alex ', 19)
Print (New1)
