If we have the name of a function defined in a different module, we can convert the string to function using the getattr() function. For this, we will pass the name of the function to the getattr() function as the first argument and the name of the module as the second argument. The...
Function call: printMsg(str) Output: "Hello world" Python program to pass a string to the function # Python program to pass a string to the function# function definition: it will accept# a string parameter and print itdefprintMsg(str):# printing the parameterprint(str)# Main code# function...
First, we discussed the basics of raw strings and how we create them by using the r prefix before string declaration. We discussed the use of the repr() function to achieve the same. We also demonstrated the use of encode() and decode() functions in succession to convert string to raw ...
In Implicit type conversion, Python automatically converts one data type to another data type. This process doesn't need any user involvement. Let's see an example where Python promotes conversion of lower datatype (integer) to higher data type (float) to avoid data loss. Example 1: Convert...
To parse a string value to a float value in Python, use the float() method, which is a library function in python, it is used to convert a given string or integer value to the float value.Below is the syntax of float() method:float(string_value/integer_value) ...
'stRINg lEArn ' >>> >>> str.rjust(20) #str右对齐 ' stRINg lEArn' >>> >>> str.zfill(20) #str右对齐,左边填充0 '00000000stRINg lEArn' 大小写转换 >>> str='stRINg lEArn' >>> >>> str.upper() #转大写 'STRING LEARN' >>> ...
