Unlike most other programming language such as c, java, in which using braces to define block; Python use whitespace and indentation to define block structure.
Example 1:
x = 0;
while(x < 10):
x += 1;
y = x;
print("x = ", x);
print("y = ", y);
Example 2:
x = 0;
while(x < 10):
x += 1;
y = x;
print("x = ", x);
print("y = ", y);
IDLE, the default IDE of Python, automatically indents lines for you.
