python string in string code example

Example 1: python string contains substring

fullstring = "StackAbuse"
substring = "tack"

if fullstring.find(substring) != -1:
    print "Found!"
else:
    print "Not found!"

Example 2: modulo str python

#look like: your_srting % values
  #when:
  #your_string = "any king of character %format"
  #type(value) = tuple
# A falg can be added between the % and the format

#Exemple:

print("there is %d ducks in the lake" % 34) #>>> there is 34 duck in the lake

# Or

your_string = "%d of the %d ducks are ducklings"
values = (12, 32)
print(your_string % values) #>>> 12 of the 34 ducks are ducklings

Formaters are:
  # Strings
  %s to display as string (and do str(value) if needed)
  #Integers
  %i to display in default int form
  %d to display as a decimal integer
  %x to display as an hexadecimal intedger (with lettre in lowercase)
  %X to display as an hexadecimal intedger (with lettre in uppercase)
  %o to display as an octal integer
  %u to display as an unsigned integer
  %c to display in ascii (process "chr(value)")
  #Floats
  %f to display in default float form
  %e to display in scientific writing (with a lowercase e to expess exponent)
  %E to display in scientific writing (with an uppercase E to expess exponent)
  %g to display as an floating exponent

Example 3: python string in string
