a = 12345.98521466
print('The value of a is :{}'.format(a:0.3f))

This code is giving syntax error.What is the correct syntax for printing upto 3 decimal places in format()?

CodePudding user response：

There will be serveral ways. I provided two ways to print the value using format, as follows:

a = 12345.98521466

# solution 1: using f-string
print(f'The value of a is :{a:0.3f}')  # The value of a is :12345.985

# solution 2: using .format
print('The value of a is :{:0.3f}'.format(a))  # The value of a is :12345.985
