Passing a parameter - Function: If it is purely digital, then return: This is a string of numbers, if it is English or English plus a number, put all the English converted to uppercase

Passing a parameter - Function: If it is purely digital, then return: This is a string of numbers, if it is English or English plus a number, put all the English converted to uppercase

The first method: Custom

def lowerToUpper(s):
    d = {'a': 'A', 'b': 'B', 'c': 'C', 'd': 'D', 'e': 'E', 'f': 'F', 'g': 'G' }   # Dictionary not write the whole 

    IF s.isdigit () == True:
         return  ' This is a purely digital string ' 

    newS = "" 
    # If parameters are passed in English, and numbers 
    for item in S:
         # of the item for Analyzing (item is in each element s) 
        IF item.isdigit () == True: 
            newS + = Item
         elif item.isalpha () == True:
             IF Item in D == False: 
                newS + = Item
             the else :
                newS += d[item]
    return newS

s = 'asdfasdfasdf'
print(s.upper())

 

Operating results as follows:

ASDFASDFASDF

The second method: using built-in functions

DEF lowertoupper (s): 

    IF s.isdigit () == True:
          Print ( " It is a pure digital string " ) 

    News = "" 
    # of item1 judgment (item is in each element s) 
    for item1 in s : #for circulation in the print statement can be removed, just to see me more clearly
         iF item1.isdigit () == True:   # determine whether the digital elements 
            News + = ITEM1
             print ( " this is a digital {} " . format (ITEM1)) # format to format 
        elif item1.islower () == True:   # determine whether the element is lowercase, then uppercase letters
            + = News item1.upper ()
             Print ( " It is a lowercase} { " .format (ITEM1))
         the else :
             Print ( " It is a capital letter} { " .format (ITEM1)) 
            News + = ITEM1
     return News 


Print (lowertoupper ( " 1235aAhfkdshfk " ))

 

Results are as follows:

This is a digital 1 
it is a number 2 
which is a number 3 
which is a number 5 
which is a lower case letter a 
This is a capital letter A 
which is a lower case letter h 
which is a lowercase f 
which is a lowercase k 
this is a lowercase d 
this is a lowercase s 
which is a lower case letter h 
which is a lowercase f 
which is a lowercase K
