# Python code to demonstrate working of 
# strip(), lstrip() and rstrip()
str = "---geeksforgeeks---"
  
# using strip() to delete all '-'
print ( " String after stripping all '-' is : ", end="")
print ( str.strip('-') )
  
# using lstrip() to delete all trailing '-'
print ( " String after stripping all leading '-' is : ", end="")
print ( str.lstrip('-') )
  
# using rstrip() to delete all leading '-'
print ( " String after stripping all trailing '-' is : ", end="")
print ( str.rstrip('-') )

# Python code to demonstrate working of 
# min() and max()
str = "geeksforgeeks"
  
# using min() to print the smallest character
# prints 'e'
print ("The minimum value character is : " + min(str))
  
# using max() to print the largest character
# prints 's'
print ("The maximum value character is : " + max(str))

# Python code to demonstrate working of 
# maketrans() and translate()
from string import maketrans # for maketrans()
  
str = "geeksforgeeks"
  
str1 = "gfo"
str2 = "abc"
  
# using maketrans() to map elements of str2 with str1
mapped = maketrans( str1, str2 )
  
# using translate() to translate using the mapping
print "The string after translation using mapped elements is : "
print  str.translate(mapped) 

# Python code to demonstrate working of 
# replace()
  
str = "nerdsfornerds is for nerds"
  
str1 = "nerds"
str2 = "geeks"
  
# using replace() to replace str2 with str1 in str
# only changes 2 occurrences 
print ("The string after replacing strings is : ", end="")
print (str.replace( str1, str2, 2)) 

# Python code to illustrate expandtabs()
string = 'GEEKS\tFOR\tGEEKS'
  
# No parameters, by default size is 8
print (string.expandtabs())
  
# tab size taken as 2
print(string.expandtabs(2))
  
# tab size taken as 5
print(string.expandtabs(5))
