type_conversion.py

python编程很好的入门材料,包括讲义和源码.

#-------------------------------------------------------------------------------
# With out the explicit conversion, Python will automatically upgrade your
# addition to "floating-point" addition, which may not be what you want 
# especially if your intention was to drop the decimal places.
#-------------------------------------------------------------------------------

myInt    = 25
myFloat  = 25.12
myString = "The value of 'myInt' is "

print myInt + myFloat

# With conversion - to int
print myInt + int( myFloat )

# With conversion - to string
print myString + str( myInt )
