Python convert int to string preserving zeros

Question

i'd like to convert a decimal to a string, where zeros at the end are preserved. Using str method erases the last zeros.

Example:

number=0.20

Goal: "0.20"

e.g. using: str(number)="0.2" doesn't seem to work.

Answer 1

If you want 2 decimal places use:

number = 0.20
str_number = '%.2f' % number

Number before f indicates the desired number of places.

Answer 2

This can be done using string formatting.

"{0:.2f}".format(number)

Will return 0.20.

Doing your chosen method won't work because upon declaring number = 0.20 it omits the last zero right away. If you put that into your idle:

number = 0.20
number
0.2

So declaring number as str(number) is doing str(0.2).

Answer 3

Use the % operator with an appropriate format string:

'%1.2f' % number
=> '0.20'
