Python String : replace()


This article demonstrates how to use of replace() method in string.

The replace() method returns a copy of the string where all occurrences of a substring is replaced with another substring.

Syntax :

string.count(substring,start,end)


Parameter Values :

ParameterDescription
oldOld substring you want to replace
newNew substring which will replace the old substring
countOptional . The number of times you want to replace the old substring with the new substring

Returns :

The replace() method returns a copy of the string where the old substring is replaced with the new substring. The original string is unchanged.
Note: If count is not specified, the replace() method replaces all occurrences of the old substring with the new substring.




Sample Code :
1.
string = 'Awesome, cppsecrets'

# replacing 'cold' with 'hurt'
print(string.replace('Awesome''company'))

string = 'Let it be, let it be, let it be, let it be'

# replacing only two occurences of 'let'
print(string.replace('let'"don't let"2))
Output :
company, cppsecrets 
Let it be, don't let it be, don't let it be, let it be 


2.
string = 'company, Amazon'
replaced_string = string.replace('a''@')

# The original string is unchanged
print('Original string:', string)

print('Replaced string:', replaced_string)

string = 'let it be, let it be, let it be'

# maximum of 0 substring is replaced
# returns copy of the original string
print(string.replace('let''so'0))
Output :
Original string: company, Amazon 
Replaced string: comp@ny, Am@zon 
let it be, let it be, let it be 


Hence,we can see above function replace() replaces all occurrences of old in string with new or at most max occurrences if max given.
