I know we have a replace method to replace a substring within a string with another string. But what I want is to replace some substring within a given string with some non-string (could be any data type) values.
example -
string1='My name is val1. My age is val2 years. I was born on val3'
val1='abc'
val2=40
val3= datetime.date(1980, 1, 1)
Any ideas??
Thanks!!
Use str.format:
>>> string1 = 'My name is {0}. My age is {1} years. I was born on {2}'
>>> string1.format('abc', 40, datetime.date(1980, 1, 1))
'My name is abc. My age is 40 years. I was born on 1980-01-01'
format with a dictionary to produce very readable code.I prefer to use a dict for that because it makes it much more simple to see which argument goes where:
'My name is {val1}. My age is {val2} years. I was born on {val3}'.format(
val1 = 'abc',
val2 = 40,
val3 = datetime.date(1980, 1, 1)
)
What about this:
string1='My name is %s. My age is %s years. I was born on %s'
print(string1 % ('abc', 40, datetime.date(1980, 1, 1)))
results in:
'My name is abc. My age is 40 years. I was born on 1980-01-01'
Convert the value to string first:
>>> string1.replace("val2", str(val2))
'My name is val1. My age is 40 years. I was born on val3'
val1,val2andval3with have to have a string representation if you want them to be instring1
