Equivalent for an internal write in Python ?

[Madhusudan Singh]

Hi

I am looking to write a formatted string to a string variable :

Say I have 1.067e-01, I need to write 106.700 to some string.

In Fortran 95, this would be accomplished with a :

character(len=7) :: stringvar
real :: stringval

....

write(stringvar,'(f7.3)') stringval

How does one do something like this in Python ? I need a string formatted in
this way for one of my applications.

Uh, I'm going to assume you meant 1.067e2, because 1.067e-01 != 106.700.

character(len=7) :: stringvar
real :: stringval

...

write(stringvar,'(f7.3)') stringval

'106.700'

String formatting is described here:

stringvar = "%.3f" % stringval
